previously vmstorage may stuck in broken state until vminsert restarts
since vmstorage was marked as read-only and connection was broken to it.

* deployment/docker/victorialogs: remove outdated comment
It was added in order to indicate that it is required to build VictoriaLogs manually before starting it at the time there was no public release available.
Currently, there is a public tag and it is not required to build it from sources.

* app/vminsert: fixes readonly check
previously vminsert doesn't check readOnly state for vmstorage, since check was never performed for nil buffer
In this case every 30 second storage node loss readonly state and received some data.
It caused re-routing and possible slow down for ingestion

Disallow parsing multitenant token at auth.NewToken().
Use auth.NewTokenPossibleMultitenant() at vminsert only. All the other callers should call auth.NewToken(),
since they do not support multitenant token.
This is a follow-up for f0c06b428e
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4910
Remove extra error message when auth token is nil. The default message
about unsupported path should be more clear to the user who mistakenly
requested /multitenant path.

- Document the change at docs/CHANGELOG.md
- Set the default value for -vmstorageUserTimeout to 3 seconds. This is much better
than the 0 value, which means that TCP connection to unreachable vmstorage could block
for up to 16 minutes.
- Document -vmstorageUserTimeout at docs/Cluster-VictoriaMetrics.md
`TCP_USER_TIMEOUT` (since Linux 2.6.37) specifies the maximum amount of
time that transmitted data may remain unacknowledged before TCP will
forcibly close the connection and return `ETIMEDOUT` to the application.
Setting a low TCP user timeout allows RPC connections quickly reroute
around unavailable storage nodes during network interruptions.
`-promscrape.cluster.membersCount` by default should be `1`, like every
single vmagent is a cluster of one member on its own.
The change additionally validates that user can't set `-promscrape.cluster.membersCount`
to value lower than `1`.

The previous code could result in the following data race:
1. The s.ptwHot partition is marked to be deleted
2. ptw.decRef() is called on it
3. ptw.pt is set to nil
4. s.ptwHot.pt is accessed from concurrent goroutine, which leads to panic.
The change clears s.ptwHot under s.partitionsLock in order to prevent from the data race.
