chore: allow collab persistence and edit state behaviour to be configurable

[khorshuheng]

The following parameter values are currently hard coded:

• Maximum allowable edit count and duration
• Interval for persisting in-memory collab group to cache/disk

Allowing the above parameters to be configured will allow us to control how frequent the in-memory edit states are saved to the cache.
