lib/storage: speed up matching for common regexps in label filters
...
The following regexps have been optimized:
* 'foo.+bar'
* 'foo.+bar.+baz'
This should improve performance for matching Graphite-like metrics.

vmalert: cleanup and restructure of code to improve maintainability ( #471 )
...
The change introduces new entity `manager` which replaces
`watchdog`, decouples requestHandler and groups. Manager
supposed to control life cycle of groups, rules and
config reloads.
Groups export an ID method which returns a hash
from filename and group name. ID supposed to be unique
identifier across all loaded groups.
Some tests were added to improve coverage.
Bug with wrong annotation value if $value is used in
templates after metrics being restored fixed.
Notifier interface was extended to accept context.
New set of metrics was introduced for config reload.
