This change implements the ranged loop observer to replace the audit
chore that builds the audit queue.
The strategy employed by this change is to use a collector for each
segment range to build separate per-node segment reservoirs that are
then merge them during the join step.
In previous observer migrations, there were only a handful of tests so
the strategy was to duplicate them. In this package, there are dozens
of tests that utilize the chore. To reduce code churn and maintenance
burden until the chore is removed, this change introduces a helper that
runs tests under both the chore and observer, providing a pair of
functions that can be used to pause or run the queueing function.

The tests are forked from the chore tests with slight adaptations for
being run against the ranged loop. I also moved a benchmark for the
database from chore_test.go to db_test.go.
The pathcollector is reused as a rangedloop.Partial.

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.

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.
