067c7afebc lib/promscrape: show information on improperly configured scrape targets at the bottom of /targets page
This is a common error whith improperly configured target autodiscovery and/or relabeling.
This error leads to duplicate scraping of the same targets with the same set of labels, which leads
to duplicate samples in time series.

257521a634 lib/promscrape: properly expose statuses for targets with duplicate scrape urls at /targets page
Previously targets with duplicate scrape urls were merged into a single line on the page.
Now each target with duplicate scrape url is displayed on a separate line.

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`.

* 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
