While at it, substitute `*MergeConcurrencyLimitCh` channels with simple integer limits.

e7959094f6 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.

e4303d3d21 lib/storage: prevent possible race condition when all the goroutines exit Storage.AddRows, before goroutines other goroutines are blocked on searchTSIDsCond inside Storage.searchTSIDs 
This condition may occur after the following sequence of events:

1) A goroutine enters the loop body when len(addRowsConcurrencyCh) == cap(addRowsConcurrencyCh) inside Storage.searchTSIDs.
2) All the goroutines return from Storage.AddRows.
3) The goroutine from step 1 blocks on searchTSIDsCond.Wait() inside the loop body.

The goroutine remains blocked until the next call to Storage.AddRows, which calls searchTSIDsCond.Signal().
This may take indefinite time.

This is a follow-up commit after 12b16077c4 ,
which didn't reset the `tsidCache` in all the required places.
This could result in indefinite errors like:

    missing metricName by metricID ...; this could be the case after unclean shutdown; deleting the metricID, so it could be re-created next time

Fix this by resetting the cache inside deleteMetricIDs function.

cb92113632 lib/storage: limit the maximum concurrency for data ingestion to GOMAXPROCS 
Previously the concurrency has been limited to GOMAXPROCS*2. This had little sense,
since every call to Storage.AddRows is bound to CPU, so the maximum ingestion bandwidth
is achieved when the number of concurrent calls to Storage.AddRows is limited to the number of CPUs,
i.e. to GOMAXPROCS.

for data ingestion and/or for executing heavy queries.
