app/vmselect/promql: use lock-less approach to gather results of parallel processing for evalRollup* funcs (#4004) 
* vmselect/promql: refactor `evalRollupNoIncrementalAggregate` to use lock-less approach for parallel workers computation

Locking there is causing issues when running on highly multi-core system as it introduces lock contention during results merge.

New implementation uses lock less approach to store results per workerID and merges final result in the end, this is expected to significantly reduce lock contention and CPU usage for systems with high number of cores.

* vmselect/promql: refactor `evalRollupFuncWithSubquery` to avoid using locks

Uses same approach as `evalRollupNoIncrementalAggregate` to remove locking between workers and reduce lock contention.

app/vmselect/promql: pass workerID to the callback inside doParallel() 
This opens the possibility to remove tssLock from evalRollupFuncWithSubquery()
in the follow-up commit from @zekker6 in order to speed up the code
for systems with many CPU cores.

app/vmselect: optimize incremental aggregates a bit 
Substitute sync.Map with an ordinary slice indexed by workerID.

all: follow-up for 7a3e16e774 
- Sync the description for -httpListenAddr.useProxyProtocol command-line flag at vmagent and vmauth,
  so it is consistent with the description at vmauth and victoria-metrics
- Add a sample of panic text to docs/CHANGELOG.md, so it could be googled
- Mention the -httpListenAddr.useProxyProtocol command-line flag in the description for the bugfix

app/vmselect/netstorage: reduce tail latency during query processing 
Previously the selected time series were split evenly among available CPU cores
for further processing - e.g unpacking the data and applying the given rollup
function to the unpacked data.
Some time series could be processed slower than others.
This could result in uneven work distribution among available CPU cores,
e.g. some CPU cores could complete their work sooner than others.
This could slow down query execution.

The new algorithm allows stealing time series to process from other CPU cores
when all the local work is done. This should reduce the maximum time
needed for query execution (aka tail latency).

The new algorithm should also scale better on systems with many CPU cores,
since every CPU processes locally assigned time series without inter-CPU communications.

The inter-CPU communications are used only when all the local work is finished
and the pending work from other CPUs needs to be stealed.
