* 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format was added; * evaluation interval may be set to every particular group; * vmalert: uncomment tests * vmalert: rm outdated TODO * vmalert: fix typos in README
