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.

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.

like `gitlab_runner_jobs`. See https://gitlab.com/gitlab-org/gitlab-exporter/issues/50 for details.

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]`.
