Move groups sequence to NoteDB
This mirrors commit 5be9c31 ("Move account sequence to NoteDb"), with
the following differences:
* The group IDs go into refs/sequences/groups
* SchemaCreator creates groups, so there, we manually instantiate
Sequences.
* Since group creation is rare, there is no tuning for batch size.
This is the first step in the procedure to move the group IDs to
NoteDb. The next steps are:
* Ensure that this code is stable and rolled out
* Run the schema upgrade
* Flip the readSequenceFromNoteDb flag
* Ensure that code is stable
* Delete readSequenceFromNoteDb flag, and associated dead code.
