7a61357b5d app/vminsert/netstorage: make sure that the the data is always replicated among -replicationFactor vmstorage nodes 
Previously vminsert could write multiple copies of the data to a single vmstorage node when the ingestion rate
exceeds the maximum throughput for connections to vmstorage nodes.

b0131c79b6 lib/storage: improve search speed for time series matching Graphite whildcards such as foo.*.bar.baz 
Add index for reverse Graphite-like metric names with dots. Use this index during search for filters
like `__name__=~"foo\\.[^.]*\\.bar\\.baz"` which end with non-empty suffix with dots, i.e. `.bar.baz` in this case.

This change may "hide" historical time series during queries. The workaround is to add `[.]*` to the end of regexp label filter,
i.e. "foo\\.[^.]*\\.bar\\.baz" should be substituted with "foo\\.[^.]*\\.bar\\.baz[.]*".

75f2f3b09d app/vminsert/netstorage: improve ingestion performance when a single vmstorage node is slower than other vmstorage nodes 
Previously the ingestion performance has been limited by the slowest vmstorage node.
Now vminsert should re-route data from the slowest vmstorage node to the remaining nodes.
