[~linyiqun] At this point of time, we just wanted to have this capability on demand. The FSCK
server can use this OM DB checkpoint snapshot utility to bootstrap its metadata during initial
start or after a long period of being down. Currently, we don't see a requirement for obtaining
an older snapshot of the DB.

> We need to add an API to OM so that we can serve snapshots from the OM server.
>  - The snapshot should be streamed to fsck server with the ability to throttle network
utilization (like TransferFsImage)
