app/vmalert: update remote-write process (#5284) 
* app/vmalert: update remote-write process

* automatically retry remote-write requests on closed connections. The change should reduce the amount of logs produced in environments with short-living connections or environments without support of keep-alive on network balancers.
* increment `vmalert_remotewrite_errors_total` metric if all retries to send remote-write request failed. Before, this metric was incremented only if remote-write client's buffer is overloaded.
* increment `vmalert_remotewrite_dropped_rows_total` amd `vmalert_remotewrite_dropped_bytes_total` metrics if remote-write client's buffer is overloaded. Before, these metrics were incremented only after unsuccessful HTTP calls.

* Update docs/CHANGELOG.md

app/vmselect: return stats.seriesFetched as string instead of number 
vmalert expects string value for stats.seriesFetched, so it is impossible
switching to number without breaking compatibility with old vmalert releases :(

It is still unclear why stats.seriesFetched has string type in the first place...

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.
