mgr/DaemonServer: remove any upmaps on merging PGs

Remove any pg_upmap[_items] on pgs that are merging to ensure that they
land on the same OSDs.

This is a bit sloppy: we *could* set the source upmap to match the target
upmap (vs potentially moving both PGs to a third location, and/or then
having the balancer move the resulting PG somewhere else again), but for
now assume upmaps are not a common case and Keep It Simple.

- calculate the magnitude of our adjusted based on the max_misplaced

mon/OSDMonitor: make pgp_num track pg_num more consistently

Previously we were automatically adjusting pgp_num_target on a
pg_num_target change *only* when decreasing pg_num.  Instead, make
pgp_num (continue to) track pg_num if it currently matches.  If it ever
is set differently than pg_num, leave it different (unless/until it
matches again).

This is still slightly weird, but I think in practice it is good enough.
In the rare case that the admin manually sets pgp_num to something
different than pg_num, they probably won't also be using automagic
pg_num adjustment that might make them match and start tracking again.

the object is less than op.extent.truncate_size.

Without this change, we were always setting size =
op.extent.truncate_size, when (seq < op.extent.truncate_seq) and
(op.extent.offset + op.extent.length > op.extent.truncate_size), were both
true. This ended up in:

1. overestimating the size of the object
2. not considering the correct size of the object, for
   the later checks, which calculate op.extent.length for the read ops
3. causing crashes when trying to read more data than what was present
