WIP: Support safe time advancement on replicas in the absense of writes
Mostly getting some jenkins mileage but the design should be close
to the final one.
This is a WIP that needs to be broken down further but that summarily
adds the following:
- Add a TimeManager class: This class is responsible for tracking
safe time advancement on leaders and replicas.
- Removes the clock from MvccManager - Since safe time is now managed
by the TimeManager there is no need for Mvcc to have one internally.
- Changes how we wait for "all committed" in MvccManager. Previously
we would wait for a clean snapshot. Now we instead wait for all
transactions before the timestamp to be committed even if the
clean timestamp doesn't advance. This is because without leader
leases the safe time can go back, but moving the clean time back
would break a lot of things internally.
- Plugs the TimeManager in consensus/queue and calls its methods
appropriately.
