vmalert: set default value for datasource.queryStep to 5m (#3149)
Change default value for command-line flag `datasource.queryStep` from `0s` to `5m`.
Param `step` is added by vmalert to every rule evaluation request sent to datasource.
Before this change, `step` was equal to group's evaluation interval by default.
Param `step` for instant queries defines how far VM can look back for the last written data point.
The change supposed to improve reliability of the rules evaluation when evaluation interval
is lower than scraping interval.

The standard Snappy encoder from github.com/golang/snappy shows quite good performance number
for compressing the Prometheus remote_write proto messages according to the added benchmarks,
so there is no need in switching to github.com/klauspost/compress/s2 yet.

vmalert: always re-evaluate Annotations (#3119)
* vmalert: always re-evaluate Annotations

Previously, Annotations were evaluated only:
1. On alert creating.
2. On alert's value change.

This is premature optimization. It was assumed that since annotations
could contain only text with alert's labels or value - there is no need
in spending resources to re-compile Annotations.

Later, template function `query` was added, which can execute
arbitrary queries and return different results on every evaluation.
So if it was used in annotations, it would be executed only on init
or value change.

Another case when optimization caused an issue - annotations hot reload.
In this case, annotations of the active alert won't change even if Rule's
annotations were changed.

This fix enables Annotations re-evaluation on each iteration to resolve
issues above. It would have some impact on performance, but it is unlikely
it will be noticeable.

This reduces scrape duration for targets returning big responses.

The new feature keeps last 20 state changes of each Rule
in memory. The state are available for view on the Rule's
view page. The page can be opened by clicking on `Details`
link next to Rule's name on the `/groups` page.

States change suppose to help in investigating cases when Rule
doesn't generate alerts or records.
