Commit disables the verbosity in integration
tests after confirming that the tests run in both master and cluster
branches.

Add the ability to create a simple cluster configuration for tests that
do not verify the cluster-specific behavior but instead are focused on
the business logic tests, such as API surface or MetricsQL. For such
tests this cluster configuration will be enough in most cases.
Cluster-specific tests should continue creating custom configurations.

### Describe Your Changes
This PR continues the implementation of integration tests (#7199). It
adds the support for vm-single:
- A vmsingle app wrapper has been added
- Sample vmsingle tests that test the VM documentation related to
querying data (#7435)
- The tests use the go-cmp/{cmp,/cmpopts} packages, therefore they have
been added to ./vendor
- Minor refactoring: data objects have been moved to model.go
Advice on porting things to cluster branch:
- The build rule must include tests that start with TestVmsingle
(similarly to how TestCluster tests are skipped in master branch)
- The build rule must depend on `vmstorage vminsert vmselect` instead of
`victoria-metrics`
- The query_test.go can actually be implemented for cluster as well. To
do this the tests need to be renamed to start with TestCluster and the
tests must instantiace vm{storage,insert,select} instead of vmsingle.

### Describe Your Changes
Related issue: #7199
This is the initial version of the integration tests for cluster. See
`README.md` for details.
Currently cluster only, but it can also be used for vm-single if needed.
The code has been added to the apptest package that resides in the root
directory of the VM codebase. This is done to exclude the integration
tests from regular testing build targets because:
- Most of the test variants do not apply to integration testing (such as
pure or race).
- The integtation tests may also be slow because each test must wait for
2 seconds so vmstorage flushes pending content). It may be okay when
there are a few tests but when there is a 100 of them running tests will
require much more time which will affect the developer wait time and CI
workflows.
- Finally, the integration tests may be flaky especially short term.
An alternative approach would be placing apptest under app package and
exclude apptest from packages under test, but that is not trivial.
The integration tests rely on retrieving some application runtime info
from the application logs, namely the application's host:port. Therefore
some changes to lib/httpserver/httpserver.go were necessary, such as
reporting the effective host:port instead the one from the flag.

### Describe Your Changes
fsync() ensures that the data is written to disk. In production this is
needed for data durability. However, during the development, when the
unit tests are run, this level of durability is not needed. Therefore
fsync() can be disabled which will makes test runs two times faster.
The disabling is done by setting the `DISABLE_FSYNC_FOR_TESTING`
environment variable. The valid values for this variable are the same as
the values of the arg of `go doc strconv.ParseBool`:
```
1, t, T, TRUE, true, True, 0, f, F, FALSE, false, False.
```
Any other value means `false`.
The variable is set for all test build targets. Compare running times:
Build Target | DISABLE_FSYNC_FOR_TESTING=0 | DISABLE_FSYNC_FOR_TESTING=1
----------------- | ------------------------------------------------ |
-------------------------------------------------
make test | 1m5s | 0m22s
make test-race | 3m1s | 1m42s
make test-pure | 1m7s | 0m20s
make test-full | 1m21s | 0m32s
make test-full-386 | 1m42s | 0m36s
When running tests for a given package, fsync can be disabled as
follows:
```shell
DISABLE_FSYNC_FOR_TESTING=1 go test ./lib/storage
```
Disabling fsync() is intended for testing purposes only and the name of
the variables reflects that.
What could also have been done but haven't:
- lib/filestream/filestream.go: `Writer.MustFlush()` also uses f.Sync()
but nothing has been done to it, because the Writer.MustFlush() is not
used anywhere in the VM codebase. A side question: what is the general
policy for the unused code?
- lib/filestream/filestream.go: Writer.Write() calls `adviceDontNeed()`
which calls unix.Fdatasync(). Disabling it could potentially improve
running time, but running tests with this code disabled has shown
otherwise.

### Describe Your Changes
Forcefully set permissions for release binaries to 1000:1000. This helps
to avoid issues such as
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6788 on
systems with limitations around UID:GID configuration.
"1000" UID and GID is widely used by linux distributions for the first
user in the system.

### Describe Your Changes
Implement spellcheck command:
- add cspell configuration files
- dockerize spellchecking process
- add Makefile targets
This PR adds a standalone `make spellcheck` target to check `docs/*.md` files for spelling
errors. The target process is dockerized to be run in a separate npm environment.
Some `docs/` typo fixes also included.

The `make clean-checkers` command may be useful when the locally installed checker apps are too old,
so they must be updated to the newly requested versions by `make check-all`. In this case the fix is to run
make clean-checkers check-all
This reverts commit 92b22581e6.
Reason for revert: too complex and slow approach for spellchecking task.
This approach may significantly slow down development pace. It also may take non-trivial
amounts of additional time and resources at CI/CD because of all this npm shit at cspell directory.
Note to @arkid15r : the idea with the ability to run spellchecker on all the VictoriaMetrics
codebase is great. But this shouldn't be mandatory pre-commit check. It is enough to have
a Makefile rule like `make spellcheck`, which could be run manually whenever spellcheck is needed
(e.g. once per month or once per quarter).
VictoriaLogs has its own release schedule, so it must be released separately via:
make publish-victoria-logs release-victoria-logs
TODO: sync VictoriaLogs and VictoriaMetrics releases after VictoriaLogs goes out of preview stage.
This will simplify release process and upgrades at user side.
This reverts commit 20b18e9feb.
Reason for revert: running goimports on `make check-all` introduces the following issues:
- It runs only on modified files, which weren't commited yet into git repository.
This means the formatting for the remaining files becomes different comparing to the formatting
for the changed files. This also means that the goimports has no any effect
at github actions and when the changed code is already commited to git repository.
- `gomiports` performs formatting in the same way as gofmt, so `make fmt` becomes unnecessary.
But when `gofmt` is substituted with `goimports`, then it performs unnecessary formatting for *.qtpl.go files.
It is possible to make a hack, which will prepare a list of all the *.go files at lib/ and app/
without the *.qtpl.go files, and then feed this list to `goimports`, but this looks too fragile
for the task of just fixing the ordering of Go imports.
So it is better to leave source code formatting as is with `gofmt`, while manually fixing improper ordering
of Go import from time to time in dedicated commits until better solution arises.
* make: add goimports task
Adds task to fix imports formatting implace.
Formats imports into:
- native library
- external libraries
- local packages based on github.com/VictoriaMetrics/VictoriaMetrics prefix

* make: run goimports only for changed files
Applying goimports to all existing files would create a lot of problems with cherry-picking changes between different branches used for development. To avoid this it was decided to only run goimports on changed files to fix formatting gradually.
