app/vmagent/remotewrite: do not drop persistent queues when -remoteWrite.multitenantURL is set
It is unsafe to drop persistent queues when -remoteWrite.multitenantURL command-line flag is set,
since these queues are created on demand when a new sample for the given tenant is pushed
to the remote storage.

This addresses https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5357
The issue has been appeared in the commit f3a51e8b1d

lib/protoparser/promremotewrite: fall back to zstd decoding if Snappy-decoding fails (#5344)
This case is possible after the following steps:
1. vmagent successfully performed handshake with the -remoteWrite.url and the remote storage supports zstd-compressed data.
2. remote storage became unavailable or slow to ingest data, vmagent compressed the collected data into blocks with zstd and puts these blocks to persistent queue on disk.
3. vmagent restarts and the remote storage is unavailable during the handshake, then vmagent falls back to Snappy compression.
4. vmagent starts sending zstd-compressed data from persistent queue to the remote storage, while falsely advertizing it sends Snappy-compressed data.
5. The remote storage receives zstd-compressed data and fails unpacking it with Snappy.

The solution is the same as 12cd32fd75, just fall back to zstd decompression if Snappy decompression fails.

lib/handshake: check for deadline in Read and Write methods (#5327)
The buffered connection could have exceeded the underlying connection
deadline during reading or writing to an internal buffer.
With this change, buffered connection struct additionally checks
for a deadline in Read/Write methods.

app/vmselect/promql: properly handle duplicate series when merging cached results with the results obtained from the database
evalRollupFuncNoCache() may return time series with identical labels (aka duplicate series)
when performing queries satisfying all the following conditions:

- It must select time series with multiple metric names. For example, {__name__=~"foo|bar"}
- The series selector must be wrapped into rollup function, which drops metric names. For example, rate({__name__=~"foo|bar"})
- The rollup function must be wrapped into aggregate function, which has no streaming optimization.
  For example, quantile(0.9, rate({__name__=~"foo|bar"})

In this case VictoriaMetrics shouldn't return `cannot merge series: duplicate series found` error.
Instead, it should fall back to query execution with disabled cache.

Also properly store the merged results. Previously they were incorrectly stored because of a typo
introduced in the commit 41a0fdaf39

dashboards: use version instead of short_version in annotations
`version` label won't show the difference if various flavors of the same
version were deployed. But `short_version` will.

For example, on the sandbox env we test VM builds before new version release.
Without this change, the version update won't be visible on dashboard.

lib/htmlcomponents: use relative links for the top page and for favicon.ico
This allows hiding VictoriaMetrics components behind proxies with arbitrary path prefixes.
For example, vmagent HTTP handlers can be served via /vmagent/ path prefix:

- http://proxy/vmagent/targets
- http://proxy/vmagent/service-discovery

The path prefix can be arbitrary. For example, below are vmagent urls
for /tenantID/vmagent/ path prefix:

- http://proxy/tenantID/vmagent/targets
- http://proxy/tenantID/vmagent/service-discovery

While at it, consistently serve favicon.ico from any path directory.

- Add ability to disable backend TLS verification for all the users via -backend.tlsInsecureSkipVerify command-line flag.
  This flag may be useful when -auth.config contains big number of users, and every user must disable backend TLS verification.

- Add ability to specify TLS Root CA via tls_ca_file option at per-user basis and via -backend.tlsCAFile command-line flag
  across all the users.

lib/blockcache: do not cache entries, which were attempted to be accessed 1 or 2 times
Previously entries which were accessed only 1 time weren't cached.
It has been appeared that some rarely executed heavy queries may read indexdb block twice
in a row instead of once. There is no need in caching such a block then.
This change should eliminate cache size spikes for indexdb/dataBlocks when such heavy queries are executed.

Expose -blockcache.missesBeforeCaching command-line flag, which can be used for fine-tuning
the number of cache misses needed before storing the block in the caching.

app/vmselect/promql: optimize repeated SLI-like instant queries with lookbehind windows >= 1d
Repeated instant queries with long lookbehind windows, which contain one of the following rollup functions,
are optimized via partial result caching:

- sum_over_time()
- count_over_time()
- avg_over_time()
- increase()
- rate()

The basic idea of optimization is to calculate

  rf(m[d] @ t)

as

  rf(m[offset] @ t) + rf(m[d] @ (t-offset)) - rf(m[offset] @ (t-d))

where rf(m[d] @ (t-offset)) is cached query result, which was calculated previously

The offset may be in the range of up to 1 hour.
