HADOOP-18671. Add recoverLease(), setSafeMode(), isFileClosed() as interfaces to hadoop-common (#5553) (#5619) 
* HADOOP-18671. Add recoverLease(), setSafeMode(), isFileClosed() as interfaces to hadoop-common (#5553)

The HDFS lease APIs have been replicated as interfaces in hadoop-common so other filesystems can
also implement them.  Applications which use the leasing APIs should migrate to the new
interface where possible.
