Per collection start or stop

Explicit per-collection start/stop
The aidr-collector requires explicit per-collection start/stop to operate. This start/stop command is issued aidr-manager through the aidr-collector API.
The aidr-persister also requires explicit per-collection start/stop to operate. This start/stop command is issued by aidr-collector through the aidr-persister API. This is legacy of an old design, ideally the persister should not require explicit start/stop.
No explicit per-collection start/stop
The aidr-output and aidr-analytics module do not require explicit per-collection start/stop.
Instead, each of these modules independently does the following:
- listen to the Redis queue to which aidr-tagger writes
- every time it detects a new collection, create a new in-memory data structure for that collections
- in-memory data structures are destroyed if inactive for a long time
