lib/storage: explicitly pass dedupInterval to DeduplicateSamples() and deduplicateSamplesDuringMerge() 
This improves the code readability and debuggability, since the output of these functions
stops depending on global state.

app: use relative paths instead of absolute paths for the supported http handlers on the main page 
This allows hiding VictoriaMetrics components behind proxies, which serve pages at different path prefixes

ef7e2af8f5 app: respect CPU limits set via cgroups

4c02e496f7 lib/fs: do not postpone directory removal on NFS error 
Continue trying to remove NFS directory on temporary errors for up to a minute.

The previous async removal process breaks in the following case during VictoriaMetrics start

- VictoriaMetrics opens index, finds incomplete merge transactions and starts replaying them.
- The transaction instructs removing old directories for parts, which were already merged into bigger part.
- VictoriaMetrics removes these directories, but their removal is delayed due to NFS errors.
- VictoriaMetrics scans partition directory after all the incomplete merge transactions are finished
  and finds directories, which should be removed, but weren't still removed due to NFS errors.
- VictoriaMetrics panics when it finds unexpected empty directory.
