c9472e4f3a all: use github.com/klauspost/compress/gzip instead of compress/gzip
`github.com/klauspost/compress/gzip` is more optimized than `compress/gzip`.
This gives better gzip compression and decompression speeds.

d0d258b314 app/vmselect: limit the default value for -search.maxConcurrentRequests, so it plays well on systems with more than 16 vCPUs
A single heavy request can saturate all the available CPUs, so let's limit the number of concurrent requests to lower value.
This will give more chances for executing insert path.

These functions can be used for calculating Hoeffding bounds
for `m` over `d` time range and for the given `phi` in the range `[0..1]`.

46bfdbe6cf app/vmselect/promql: do not take into account the previous point before time window in square brackets for min_over_time, max_over_time, rollup_first and rollup_last functions
This makes the behaviour for these functions similar to Prometheus when processing broken time series with irregular data points
like `gitlab_runner_jobs`. See https://gitlab.com/gitlab-org/gitlab-exporter/issues/50 for details.

164278151f app/vmselect/promql: add aggr_over_time(("aggr_func1", "aggr_func2", ...), m[d]) function
This function can be used for simultaneous calculating of multiple `aggr_func*` functions
that accept range vector. For example, `aggr_over_time(("min_over_time", "max_over_time"), m[d])`
would calculate `min_over_time` and `max_over_time` for `m[d]`.
