6a75c95194 lib/promscrape: remove labels starting with __meta_ after applying relabel_configs as Prometheus does 
This should reduce CPU load during scraping when target discovery generates
big number of `__meta_*` labels (for instance, k8s discovery).

See https://www.robustperception.io/life-of-a-label for details.

01d7d799dc lib/promscrape: rename 'scrape_config->scrape_limit' to 'scrape_config->sample_limit' 
`scrape_config` block from Prometheus config contains `sample_limit` field,
while in `vmagent` this field was mistakenly named as `scrape_limit`.

Vmalert/rules eval (#400) 
* Initial rules evaluation support.

Rules are now store alerts state in private field `alerts`. Every evaluation updates
the alerts and state. Every unique metric received from datastore represents a unique alert,
uniqueness is guaranteed by hashing ordered labelset.

* merge with master

* cleanup

* support endAt parameter as 3*evaluationInterval for active alerts

* make golint happy
