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.

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

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

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.
