Unassign a region. Unassign will close region in current location and then
reopen it again.  Pass 'true' to force the unassignment ('force' will clear
all in-memory state in master before the reassign. If results in
double assignment use hbck -fix to resolve. To be used by experts).
Use with caution.  For expert use only.  Examples:

  hbase> unassign 'REGIONNAME'
  hbase> unassign 'REGIONNAME', true
  hbase> unassign 'ENCODED_REGIONNAME'
  hbase> unassign 'ENCODED_REGIONNAME', true
EOF

          admin.unassign(region_name, force)
        end
      end
