Mateusz Mandera 512f4d1476 presence: Backend implementation of the last_update_id API.
This builds on top of 016880f54d which
maintains correct .last_update_id for UserPresence objects; now we add
the related API changes to utilize it.

Mateusz Mandera 0dca8f2a38 models: New PresenceSequence model and UserPresence.last_update_id col.
Migration plan:
1. Add NULLable .last_update_id column to UserPresence with default 0
   for new objects.
2. Backfill the value to 0 for old UserPresences, can be done in the
   background while server is running.
3. Make the column non-NULL.
4. Add new model PresenceSequence and create its rows for old realms.
