### Describe Your Changes
Currently the alert descrption considers only one end of the connection
(vmagent). While saturation can also be caused by slowness of the
receiving components (vminsert, vmstorage). Update the alert description
with a brief suggestion to also check the dashboards of these
components.

Previously, time series with labels exceeding the configured limits were truncated and written to storage, potentially causing data inconsistency. This could lead to collisions between time series and make it difficult to identify the source due to truncated labels.
This commit changes the behavior:
* Such time series are now rejected outright.
* Rejected time series are logged to stdout, and corresponding counters are incremented.
* removes `vm_too_long_label_values_total`, `vm_too_long_label_names_total`, `vm_metrics_with_dropped_labels_total` metrics.
* adds new values `[too_many_labels,too_long_label_name,too_long_label_value]` to `reason` label of the `vm_rows_ignored_total` metric name

### Describe Your Changes
Many users are running k8s-stack in multiple kubernetes clusters and to
configure a proper routing in alertmanager it's required to support
`cluster` label in alerting rules. It's now implemented in helm-chart
hack scripts, but it's tricky part to define if cluster label should be
added or not, when functions has no `by` expression. Updated existing
alerts to provide later an ability to inject cluster label later
Also take into an account `storage.minFreeDiskSpaceBytes` in
`DiskRunsOutOfSpace` alerts
