29bbab0ec9 lib/storage: remove prioritizing of merging small parts over merging big parts, since it doesn't work as expected
The prioritizing could lead to big merge starvation, which could end up in too big number of parts that must be merged into big parts.

Multiple big merges may be initiated after the migration from v1.39.0 or v1.39.1. It is OK - these merges should be finished soon,
which should return CPU and disk IO usage to normal levels.

The function is useful for building heatmaps in Grafana from too big number of buckets.

0bff96fe4b lib/storage: prioritize data ingestion over heavy queries
Heavy queries could result in the lack of CPU resources for processing the current data ingestion stream.
Prevent this by delaying queries' execution until free resources are available for data ingestion.

Expose `vm_search_delays_total` metric, which may be used in for alerting when there is no enough CPU resources
for data ingestion and/or for executing heavy queries.

156c83d112 app/vmalert: support multiple notifier urls (#584) (#590)
* app/vmalert: support multiple notifier urls (#584)

User now can set multiple notifier URLs in the same fashion
as for other vmutils (e.g. vmagent). The same is correct for
TLS setting for every configured URL. Alerts sending is done
in sequential way for respecting the specified URLs order.

* app/vmalert: add basicAuth support for notifier client (#585)

The change adds possibility to set basicAuth creds for notifier
client in the same fasion as for remote write/read and datasource.

of the main function.

a586b8b6d4 app/vminsert/netstorage: do not re-route every time series to more than two vmstorage nodes when certain vmstorage nodes are temporarily slower than the rest of them
Previously vminsert may spread data for a single time series across all the available vmstorage nodes
when vmstorage nodes couldn't handle the given ingestion rate. This could lead to increased usage
of CPU and memory on every vmstorage node, since every vmstorage node had to register all the time
series seen in the cluster. Now a time series may spread to maximum two vmstorage nodes under heavy load.
Every time series is routed to a single vmstorage node under normal load.
