What changes were proposed in this pull request?

The ozone debug recover command that is currently used for lease recovery has a few problems:

• It modifies the cluster, so it should not be under debug.
• The name does not specify that it deals with leases.
• It uses a standard API from the FileSystem interface unlike other low level tools in this package.

The command is unique because it goes through the FileSystem interface but is not exposed through the fs command line in Hadoop or Ozone. For these reasons, we propose moving this command to its own Ozone subcommand: ozone admin om lease recover. This also allows other lease related subcommands (like querying of existing leases) to be added in the future.
