osd: maintain up_epoch AND boot_epoch; revise OSDSuperblock accordingly

In order to make the superblock clean interval meaningful after we
are marked down and then up again (over the life of a single
cosd process insance), we track both boot_epoch and up_epoch,
and keep [boot_epoch,clean_thru] in the superblock.

This avoids seeing crashed pgs when and osd is wrongly marked down
and the osd marks itself up again.
