lib/license: cleanups and prettifications for log messages and docs related to licensing

- Make more clear the docs at docs/enterprise.md, so readers could figure out faster on how to obtain enterprise key and how to pass it to VictoriaMetrics Enterprise components. - Fix examples at docs/enterprise.md, which were referring to non-existing `-license-file` command-line flag. The `-licenseFile` command-line flag must be used instead. - Improve the description of `-license*` command-line flags, so users could understand faster how to use them. - Improve the warning message, which is emitted when the deprecated -eula command-line flag is passed, so the user could figure out how to switch faster to -license* command-line flags. - Disallow running VictoriaMetrics components with both -license and -licenseFile command-line flags. - Disallow running VictoriaMetrics components when -licensFile points to an empty file. - Consistently use the phrase "This flag is available only in Enterprise binaries" across all the enterprise-specific command-line flags. - Remove unneeded level of indirection for `noLicenseMessage` and `expiredMessage` string contants in order to improve code readability and maintainability. - Remove unneded `return` statements after `logger.Fatalf()` calls, since these calls exit the app and never return. - Make sure that the info log message about successful license verification is emitted when the license is verified successfully. Previously the error message could be logged when the license payload is invalid or if it misses some required features.

+* `-licenseFile` - this flag accepts a path to file with VictoriaMetrics Enterprise license key,
+  which can be obtained at [this page](https://victoriametrics.com/products/enterprise/trial/) . Use either `-license` or `-licenseFile`, but not both.
+* `-license.forceOffline` - enables offline verification of VictoriaMetrics Enterprise license key. Contact us via [this page](https://victoriametrics.com/products/enterprise/)
+  if you need license key, which can be verified offline without the need to connect to VictoriaMetrics license server.
+
+For example, the following command runs VictoriaMetrics Enterprise binary with the Enterprise license
+obtained at [this page](https://victoriametrics.com/products/enterprise/trial/):
+
+```console
+wget https://github.com/VictoriaMetrics/VictoriaMetrics/releases/download/v1.94.0/victoria-metrics-linux-amd64-v1.94.0-enterprise.tar.gz
+tar -xzf victoria-metrics-linux-amd64-v1.94.0-enterprise.tar.gz
+./victoria-metrics-prod -license=BASE64_ENCODED_LICENSE_KEY
+```
+
+Alternatively, VictoriaMetrics Enterprise license can be stored in the file and then referred via `-licenseFile` command-line flag:
+
+```console
+./victoria-metrics-prod -licenseFile=/path/to/vm-license
+```
+
+### Docker images
+
+It is allowed to run VictoriaMetrics Enterprise components in [cases listed here](#valid-cases-for-victoriametrics-enterprise).
+
+Docker images for VictoriaMetrics Enterprise are available [at VictoriaMetrics DockerHub](https://hub.docker.com/u/victoriametrics).
+Enterprise docker images have `enterprise` suffix in their names. For example, `victoriametrics/victoria-metrics:v1.94.0-enteprise`.
+
+In order to run Docker image of VictoriaMetrics Enterprise component, it is required to provide the license key via command-line
+flag as described [here](#binary-releases).
+
+Enterprise license key can be obtained at [this page](https://victoriametrics.com/products/enterprise/trial/).
+
+For example, the following command runs VictoriaMetrics Enterprise Docker image with the specified license key:
+
+```console
+docker run --name=victoria-metrics victoriametrics/victoria-metrics:v1.94.0-enteprise -license=BASE64_ENCODED_LICENSE_KEY
+```
+
+Alternatively, the license code can be stored in the file and then referred via `-licenseFile` command-line flag:
+
+```console
+docker run --name=victoria-metrics -v /vm-license:/vm-license  victoriametrics/victoria-metrics:v1.94.0-enteprise -licenseFile=/path/to/vm-license
+```
+
+Example docker-compose configuration:
+```yaml
+version: "3.5"
+services:
+  victoriametrics:
+    container_name: victoriametrics
+    image: victoriametrics/victoria-metrics:v1.94.0
+    ports:
+      - 8428:8428
+    volumes:
+      - vmdata:/storage
+      - /vm-license:/vm-license
+    command:
+      - "-storageDataPath=/storage"
+      - "-licenseFile=/vm-license"
+volumes:
+  vmdata: {}
+```
+
+The example assumes that the license file is stored at `/vm-license` on the host.
+
+### Helm charts
+
+It is allowed to run VictoriaMetrics Enterprise components in [cases listed here](#valid-cases-for-victoriametrics-enterprise).
+
+Helm charts for VictoriaMetrics Enterprise components are available [here](https://github.com/VictoriaMetrics/helm-charts).
+
+In order to run VictoriaMetrics Enterprise helm chart it is required to provide the license key via `license` value in `values.yaml` file
+and adjust the image tag to the Enterprise one as described [here](#docker-images).
+
+Enterprise license key can be obtained at [this page](https://victoriametrics.com/products/enterprise/trial/).
+
+For example, the following `values` file for [VictoriaMetrics single-node chart](https://github.com/VictoriaMetrics/helm-charts/tree/master/charts/victoria-metrics-single)
+is used to provide key in plain-text:
+
+```yaml
+server:
+  image:
+    tag: v1.94.0-enterprise 
+
+license:
+  key: {BASE64_ENCODED_LICENSE_KEY}
+```
+
+In order to provide key via existing secret, the following values file is used:
+
+```yaml
+server:
+  image:
+    tag: v1.94.0-enterprise 
+
+license:
+  secret:
+    name: vm-license
+    key: license
+```
+
+Example secret with license key:
+
+```yaml
+apiVersion: v1
+kind: Secret
+metadata:
+  name: vm-license
+type: Opaque
+data:
+  license: {BASE64_ENCODED_LICENSE_KEY}
+```
+
+Or create secret via `kubectl`:
+```console
+kubectl create secret generic vm-license --from-literal=license={BASE64_ENCODED_LICENSE_KEY}
+```
+
+### Kubernetes operator
+
+It is allowed to run VictoriaMetrics Enterprise components in [cases listed here](#valid-cases-for-victoriametrics-enterprise).
+
+VictoriaMetrics Enterprise components can be deployed via [VictoriaMetrics operator](https://docs.victoriametrics.com/operator/).
+In order to use Enterprise components it is required to provide the license key via `license` field and adjust the image tag to the enterprise one.
+
+Enterprise license key can be obtained at [this page](https://victoriametrics.com/products/enterprise/trial/).
+
+For example, the following custom resource for [VictoriaMetrics single-node](https://docs.victoriametrics.com/Single-server-VictoriaMetrics.html) 
+is used to provide key in plain-text:
+
+```yaml
+apiVersion: operator.victoriametrics.com/v1beta1
+kind: VMSingle
+metadata:
+  name: example-vmsingle
+spec:
+  retentionPeriod: "1"
+  license:
+    key: {BASE64_ENCODED_LICENSE_KEY}
+  image:
+    tag: v1.94.0-enterprise 
+```
+
+In order to provide key via existing secret, the following custom resource is used:
+
+```yaml
+apiVersion: operator.victoriametrics.com/v1beta1
+kind: VMSingle
+metadata:
+  name: example-vmsingle
+spec:
+  retentionPeriod: "1"
+  license:
+    keyRef:
+      name: vm-license
+      key: license
+  image:
+    tag: v1.94.0-enterprise 
+```
+
+Example secret with license key:
+
+```yaml
+apiVersion: v1
+kind: Secret
+metadata:
+  name: vm-license
+type: Opaque
+data:
+  license: {BASE64_ENCODED_LICENSE_KEY}
+```
+
+Or create secret via `kubectl`:
+```console
+kubectl create secret generic vm-license --from-literal=license={BASE64_ENCODED_LICENSE_KEY}
+```
+
+See full list of CRD specifications [here](https://docs.victoriametrics.com/operator/api.html).
+
+## Monitoring license expiration
+
+All the VictoriaMetrics Enterprise components expose the following metrics at the `/metrics` page:
+
+* `vm_license_expires_at` - license expiration date in unix timestamp format
+* `vm_license_expires_in_seconds` - the number of seconds left until the license expires
+
+Example alerts for [vmalert](https://docs.victoriametrics.com/vmalert.html) based on these metrics:
+
+{% raw %}
+```yaml
+groups:
+  - name: vm-license
+    # note the `job` label and update accordingly to your setup
+    rules:
+      - alert: LicenseExpiresInLessThan30Days
+        expr: vm_license_expires_in_seconds < 30 * 24 * 3600
+        labels:

+          description: "{{ $labels.instance }} of job {{ $labels.job }} license expires in {{ $value | humanizeDuration }}. 
+            Please make sure to update the license before it expires."
+
+      - alert: LicenseExpiresInLessThan7Days
+        expr: vm_license_expires_in_seconds < 7 * 24 * 3600
+        labels:
