The scrape manage receiver's channel now just saves the target sets
and another backgorund runner updates the scrape loops every 5 seconds.
This is so that the scrape manager doesn't block the receiving channel
when it does the long background reloading of the scrape loops.
Active and dropped targets are now saved in each scrape pool instead of
the scrape manager. This is mainly to avoid races when getting the
targets via the web api.
When reloading the scrape loops now happens in parallel to speed up the
final disared state and this also speeds up the prometheus's shutting
down.
Also updated some funcs signatures in the web package for consistency.

Removing a final dot changes the meaning of the name and can cause
extra DNS lookups as the resolver traverses its search path.

* tidy up the discovery logs,updating loops and selects
few objects renamings
removed a very noise debug log on the k8s discovery. It would be usefull
to show some summary rather than every update as this is impossible to
follow.
added most comments as debug logs so each block becomes self
explanatory.
when the discovery receiving channel is full will retry again on the
next cycle.

* discovery: coalesce identical SD configurations
Instead of creating as many SD providers as declared in the
configuration, the discovery manager merges identical configurations
into the same provider and keeps track of the subscribers. When
the manager receives target updates from a SD provider, it will
broadcast the updates to all interested subscribers.
