osd,OSDMonitor: try to protect against ec overwrites with filestore

This isn't perfect, but it's better than nothing. Prevent enabling the
allow_ec_overwrites flag if any of a sample of pgs in the pool map to
osds using filestore. This mainly protects filestore-only clusters
from enabling it.

If a filestore osd is started later, warn in the cluster log when it
gets a pg with ec overwrites enabled.
