We want to eliminate usages of LoopSegmentEntry.Pieces, because it is
costing a lot of cpu time to look up node IDs with every piece of every
segment we read.
In this change, we are eliminating use of LoopSegmentEntry.Pieces in the
node tally observer (both the ranged loop and segments loop variants).
It is not necessary to have a fully resolved nodeID until it is time to
store totals in the database. We can use NodeAliases as the map key
instead, and resolve NodeIDs just before storing totals.

Segments loop have build-in sanity check to verify if number of segments
processed by loop is roughly fine. We want to have the same verification
for ranged loop.

Additional elements added:
* monkit metric for observers methods like Start/Fork/Join/Finish to
be able to check how much time those methods are taking
* few more logs e.g. entries with processed range
* segmentsProcessed metric to be able to check loop progress

Peer for generating bloom filters will be able to use ranged loop.
As an addition some cleanup were made:
* remove unused parts of GC BF peer (identity, version control)
* added missing Close method for ranged loop service
* some additional tests added

TestLoopContinuesAfterObserverError was failing due to system
granularity measuring the duration as 0.
TestDialer_DialTimeout was failing due to connection failure came with a
delay and wasn't being handled.

implemented observer and partial, created new structures to keep mon
metrics remain in same way as in segment loop

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:

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.

interval per observer, etc.
