44c51c627f vmalert: Add recording rules support. (#519) 
* vmalert: Add recording rules support.

Recording rules support required additional service refactoring since
it wasn't planned to support them from the very beginning. The list
of changes is following:
* new entity RecordingRule was added for writing results of MetricsQL
expressions into remote storage;
* interface Rule now unites both recording and alerting rules;
* configuration parser was moved to separate package and now performs
more strict validation;
* new endpoint for listing all groups and rules in json format was added;
* evaluation interval may be set to every particular group;

* vmalert: uncomment tests

* vmalert: rm outdated TODO

* vmalert: fix typos in README

f41a01332a app/vminsert/netstorage: evenly distribute rerouted rows among all the availalbe storage nodes

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[.]*".
