c86286ec1d app/vmselect/promql: do not ajdust offset value provided in the query 
Previously it could be modified in order to improve response cache hit ratio.
This is unneeded, since cache hit ratio should remain good because the query time range
should be already aligned to multiple of `step` values.

adds escape for CRLF (#984)

46dba00756 lib/storage: remove stale parts as soon as they go outside the configured retention 
Previously such parts could remain undeleted for long durations until they are merged with other parts.
