app/vminsert: increase default value for -insert.maxQueueDuration
from 30s to 60s

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.

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]`.
