Add node tally ranged loop observer and partial.
Add node tally randed observer to range loop peer.
Add config flag to select which loop to use for node tally.
Update satellite core to use segement/ranged loop based on a flag.
Duplicate existing node tally test but using ranged loop.

Small cleanups of the observer stats init code:
1. Use sync.Once for race free addition to the monitoring chain
(purely defensive)
2. Set the observer durations before adding to the monitoring chain on
first use.
3. observerDurations slice does not need to be initialized to non-nil

When an observer errors we still want to finish the other observers.
This changes store the error and continues the loop, skipping
the observer which errored out and setting the duration metric to -1.
When the error occurs in the process stage, it does continue the other
ranges of the same observer. It removes the observer entirely after the process
stage. To improve this would make it more complex due to race
conditions.

Add option AsOfSystemTime to segment provider to make it equivalent to
the old segment loop.
There's no comment on what it does because it's pretty complex and
makes no sense, but we can improve it later.

Add an observer to monitor ranged segment loop progress.
Tested by running the segment loop in storj-up and navigating to
http://<container>:11111/mon/stats and there is the entry:
rangedloop-live,scope=storj.io/storj/satellite/metabase/rangedloop numSegments=364523630000.000000

Support interruption of the ranged segment loop through context.

Change-Id: Iae0260e250f8ea33affed95c6592a1f42df384eb
added in storj-sim rangedloop for each satellite, to verify it works for metrics oveserver,
removed identity from rangedloop peer as we never use it, added logs on service run, added loop
to service instead of endless for loop, interval value to config

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
Change-Id: Ief131d34001dd5d3ba1d7be6f161986e1f66440d
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.
