cf69b1ea6f app/vmselect/promql: add buckets_limit(k, buckets) function, which limits the number of buckets per time series to k 
This function works with both Prometheus-style and VictoriaMetrics-style buckets.
The function removes buckets with the lowest values in order to reserve the highest precision.
The function is useful for building heatmaps in Grafana from too big number of buckets.

Feat/query list vmselect (#575) 
* feat(vmselect): add support for listing current running queries and canceling specific query

* fix(vmselect): change current queries' pid from int64 counter to uuid

* feat(vmselect): add auth to internal operations like `/resetRollupResultCache`, `/query/list` and `/query/kill`. add flag `internalAuthKey` for these auth

* fix(vmselect): add more info to current queries

* review: delete some unnecessary code and use function instead of init

* review: returen *queriesMap in newQueriesMap

* review: delete unused var in struct queriesMap, add comments to exported functions

* review: add return if error occurs

* feat(vmselect): truncate query string in current running query list API since the size of query string might be large;
                use query string's pointer in struct `query` for the same reason;
		add query info API to get full access of query's info;

b6d88bac04 vendor: use github.com/VictoriaMetrics/fasthttp instead of github.com/fasthttp/fasthttp 
The upstream fasthttp may contain issues like 996610f021 ,
plus a code that isn't used by VictoriaMetrics. So let's use a private copy under our control instead.
