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.

8b14572f70 app/vmselect/promql: add hoeffding_bound_upper(phi, m[d]) and hoeffding_bound_lower(phi, m[d]) functions
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]`.

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]`.

72345eb5bd lib/{mergeset,storage}: make sure pending transaction deletions are finished before and after runTransactions call.
`runTransactions` call issues async deletions for transaction files. The previously issued transaction deletions
can race with the next call to `runTransactions`. Prevent this by waiting until all the pending transaction
deletions are funished in the beginning of `runTransactions`. Also make sure that all the pending transaction
deletions are finished before returning from `runTransactions`.
