Roman Khavronenko 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* vmalert: rm outdated TODO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
