osd/PG: store pg_info_t in leveldb (omap), purged_snaps separately
Separate the purged_snaps portion of pg_info_t (the one that gets big).
Feature #3891: osd: move purged_snaps out of info
Add a separate dirty_big_info flag so that we only update the pginfo
"biginfo" file if that state changes. This lets us avoid the cost in the
general case, like a regular PG write.
Add LEVELDBINFO feature
Put info, biginfo in leveldb
Move epoch to omap
Feature #3892: osd: move pg info into leveldb
