Bookie: run garbage collection during startup if all directories became
full.
- during bookie startup, run DiskChecker to check whether all directories
are full. if they are all full, run garbage collection to collect those deleted
ledgers to reclaim disk space. if no space could be reclaimed, fail the bookie
startup (since there is no space for replaying journals)
- optimize the gc logic: gc deleted ledgers first, and scan/gc entry
loggers later.
- move ledger index file only we tried to flush them, so it would not fail
any read requests when bookie is in ReadOnly.
