Change subject: Add a way to pin clean time advancement
......................................................................
Add a way to pin clean time advancement
In order to make OpId/Timestamp assignment to transactions
atomic, during the prepare phase, we need to let consensus
assign the timestamp, before starting a transaction in
MVCC. However we also need to make sure that clean time is
not advanced past the possible timestamps assigned.
This patch adds a pin to clean time advancement that acts
much like safe time, in the sense that it doesn't allow
clean time to be advanced past it.
This also adds a way to create and delete a pin within
a scope in a RAII way.
