Glauber Costa eb93d5f8ad database: pass a monitor as a parameter to memtable writer ...

Right now we pass a permit to the memtable writer and that permit is
used insite write_memtable_to_sstable to compose a write_monitor.

We would like to extend the write_monitor to include other things, that
right now are not available as parameters to write_memtable_to_sstable -
and which are possibly too specialized to be.

The solution for that is to pass the write_monitor instead of the permit
to the writer. Conceptually, that also makes sense because the
write_monitor is something the sstable writer is aware of. Permits, on
the other hand, are a database concept that is alien to the sstable
writer.
