This feature allows to track query requests by metric names. Tracker
state is stored in-memory, capped by 1/100 of allocated memory to the
storage. If cap exceeds, tracker rejects any new items add and instead
registers query requests for already observed metric names.
This feature is disable by default and new flag:
`-storage.trackMetricNamesStats` enables it.
New API added to the select component:
* /api/v1/status/metric_names_stats - which returns a JSON
object
with usage statistics.
* /admin/api/v1/status/metric_names_stats/reset - which resets internal
state of the tracker and reset tsid/cache.
New metrics were added for this feature:
* vm_cache_size_bytes{type="storage/metricNamesUsageTracker"}
* vm_cache_size{type="storage/metricNamesUsageTracker"}
* vm_cache_size_max_bytes{type="storage/metricNamesUsageTracker"}

Initially delete_series API wasn't implemented for mulitenant auth token.
This commit fixes it and properly handle delete series requests for mulitenant auth token.
It also adds integration tests for this case.

### Describe Your Changes
These are the integration tests that confirm that instant queries may
return stale NaNs when the query contains a rollup function.
The bug was reported at #5806. There is also a fix: #7275. The tests in
this PR will be used co confirm that the fix works.
Some test refactoring has been done along the way. Sorry, couldn't
resist.

### 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.
