        <<~EOF
Enable/Disable peer modification. Returns previous state.
Examples:

  hbase> peer_modification_switch true
  hbase> peer_modification_switch false, true

The second boolean parameter means whether you want to wait until all remaining peer modification
finished, before the command returns.
