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.

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.

d15adfc917 Preserve target state across reloads.
This commit moves Scraper handling into a separate scrapePool type.
TargetSets only manage TargetProvider lifecycles and sync the
retrieved updates to the scrapePool.

TargetProviders are now expected to send a full initial target set
within 5 seconds. The scrapePools preserve target state across reloads
and only drop targets after the initial set was synced.

5b30bdb610 Change TargetProvider interface.
This commit changes the TargetProvider interface to use a
context.Context and send lists of TargetGroups, rather than
single ones.

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.

33a50e69f7 Fix a deadlock
Double acquisition of the RLock usually doesn't blow up, but if the
write lock is called for between the two RLock's, we are deadlocked.

This deadlock does not exist in release-0.17, BTW.

It can't be greater than the scrape interval. Let's just remove it.

6df1f49c13 Remove fullLabels method and fix target updating
With recent changes to a Target's internal data representation
updating by fullLabels() assigns the additional default
instance label. This breaks target identity comparison and causes
identical targets from service discovery to be constantly swapped.

825831e98f Use fingerprint for target identity comparison
So far we were using the InstanceIdentifier to compare equality of targets.
This is not always accurate, for example for the blackbox exporter where the 
actual target is in the parameter.

66767121ab Handle scrape timeout on request.
For historic reasons we were enforcing a timeout directly
via the TCP dialer. This is no longer necessary for quite a while now.
Switching to context.Context will allow us to properly terminate
requests on shutdown as well.
