Fabian Reinartz 84f74b9a84 Apply new scrape config on reload.
This commit updates a target set's scrape configuration
on reload. This will cause all running scrape loops to be
stopped and started again with new parameters.

Fabian Reinartz 1a3253e8ed Make scrape time unambigious.
This commit changes the scraper interface to accept a timestamp
so the reported timestamp by the caller and the timestamp
attached to samples does not differ.

Fabian Reinartz 05de8b7f8d Extract target scraping into scrape loop.
This commit factors out the scrape loop handling into
its own data structure.
For the transition it will be directly attached to the
target.

Fabian Reinartz 5bfa4cdd46 Simplify target update handling.
We group providers by their scrape configuration. Each provider produces
target groups with an unique identifier.

On stopping a set of target providers we cancel the target providers,
stop scraping the targets and wait for the scrapers to finish.

On configuration reload all provider sets are stopped and new ones
are created. This will make targets disappear briefly on configuration
reload. Potentially scrapes are missed but due to the consistent
scrape intervals implemented recently, the impact is minor.
