mon: OSDMonitor: smaller transactions when rebuilding full versions
Otherwise, for considerably sized rebuilds, the monitor will not only
consume vast amounts of memory, but it will also have troubles committing
the transaction. Anyway, it's also a good idea to adjust transactions to
the granularity we want, and to be fair we care that each rebuilt full map
gets to disk, even if subsequent full maps don't (those can be rebuilt
later).
Fixes: #6323
