Wire up duration measurement of observers with monkit.
Tested by attaching a SleepObserver, starting the rangedloop in storj-up
and navigating to http://<container>:11111/mon/stats. It reports the
following statistic:
completed-observer-duration,observer=*rangedlooptest.SleepObserver,scope=storj.io/storj/satellite/metabase/rangedloop duration=10.000117

Track duration of all segment loop observers. Factor out functions to
reduce size.
Still need to send the measurements out via monkit.

Some observers assume that they will observe all the segments for a
given stream, and that they will observe those segments in a sequential
stream over one or more iterations.
This change updates the range provider from rangedlooptest to provide
these guarantees.
The change also removes the Mock suffix from the provider/splitter types
since the package name (rangedlooptest) implies that the type is a test
double.

Add an abstraction rangedloop.SegmentProvider to fetch chunks of
segments from the metainfo database in parallel.

Minimal implementation of the ranged (=threaded) segment loop
service, to improve performance over the existing loop.
Has tests with a an inmemory segment database
and example observer.
Does not have yet: database link, observer duration tracking,
suspicious processed ratio guard, rate limiting, minimum execution
interval per observer, etc.

Pair uuid's to create ranges. Will be used to parallelize the segment
loop.
