app/vmselect/netstorage: optimize mergeSortBlocks function
- Use binary search instead of linear scan when locating the run of smallest timestamps
  in blocks with intersected time ranges. This should improve performance
  when merging blocks with big number of samples

- Skip samples with duplicate timestamps. This should increase query performance
  in cluster version of VictoriaMetrics with the enabled replication.

vmalert: deprecate alert's status link (#2840)
* vmalert: deprecate alert's status link

Deprecate alert's status link `/api/v1/<groupID>/<alertID>/status` in favour of
`api/v1/alerts?group_id=<group_id>&alert_id=<alert_id>"`.

The change was needed for simplifying logic in vmselect for proxying vmalert's requests.

The old alert's status link will be still supported for a few versions but will be removed in the future.

lib/storage: put the (date, metricID) entry in dateMetricIDCache just after the corresponding series is registered in the per-day inverted index
Previously the time series could be put into dateMetricIDCache without
registering in the per-day inverted index if GetOrCreateTSIDByName
finds TSID entry in the global index. This could lead to missing
series in query results.

The issue has been introduced in the commit 55e7afae3a,
which has been included in VictoriaMetrics v1.78.0

lib/storage: return marshaled metric names from SearchMetricNames
Previously SearchMetricNames was returning unmarshaled metric names.
This wasn't great for vmstorage, which should spend additional CPU time
for marshaling the metric names before sending them to vmselect.

While at it, remove possible duplicate metric names, which could occur when
multiple samples for new time series are ingested via concurrent requests.

Also sort the metric names before returning them to the client.
This simplifies debugging of the returned metric names across repeated requests to /api/v1/series

all: limit the maximum memory usage for regexp cache, which stores parsed regular expressions in MetricsQL queries
Previously the cache could store 10K unique regexps. When every regexp is huge (e.g. hundreds of kilobytes),
then the total cache size could grow to multiples of gigabytes. Now the cache size is limited by the total length
of all cached regexps. So huge regexps won't result in high memory usage for the cache.

lib/netutil.ConnPool: skip dialing remote address if the previous dial attempt was unsuccessful
If the previous dial attempt was unsuccessful, then all the new dial attempts are skipped
until the background goroutine determines that the given address can be successfully dialed.

This reduces query latency when some of vmstorage nodes are unavailable and dialing them is slow.

This should help with https://github.com/VictoriaMetrics/VictoriaMetrics/issues/711

This commit is based on ideas from the https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2756

The main differences are:

- The check for healthy/unhealthy storage nodes is moved one level lower from app/vmselect/netstorage to lib/netutil.ConnPool.
  This makes possible re-using this feature everywhere lib/netutil.ConnPool is used.
- The check doesn't take into account handshake errors for already established connections.
  Handshake errors usually mean improperly configured VictoriaMetrics cluster, so they shouldn't be ignored.

vmselect: limit end param max value by 2d in future (#2729)
* vmselect: limit `end` param max value by 2d in future

The change is applied only to service handlers like `/labels` or `/series`
and limits the `end` param by max value <= now() + 2 days. The same limit
is applied for the ingested data, so no reason to allow to request data
in future far than that.

The change is also needed for corner cases like https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2669
where too high `end` value triggers inefficient global index search.

docs/guides/migrate-from-influx.md: suggest more real-world value for -search.maxStalenessInterval
Suggest `-search.maxStalenessInterval=10s` instead of `-search.maxStalenessInterval=1ms`,
since `1ms` would result in empty graphs in most cases, since the interval between data points
on the graph is usually much higher than 1ms. For example, if the graph shows time range of one hour
and it contains 1000 points, then the interval between points on the graph would equal to
3600s/1000=3.6 seconds.
