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.

e40d015e9a vmselect: make vm_partial_results_total consistent
Metrics `vm_partial_results_total` and `vm_requests_total` serving
the similar purpose, but contain inconsistent set of labels.
This change updates `vm_partial_results_total` labels to be consistent
with `vm_requests_total`.

The change breaks backward compatibility with assumption that
`vm_partial_results_total` wasn't widely used, since it is
not documented and absent in the alerts and dashboards.

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.
