Silence data recovery output

- with changing 'client.run' to 'client.proxy.run' (9ecc538), and moving
  _format_response to the cli module, any output from data recovery is
  unformatted (i.e. a dict response like '{"id": 1}' would be displayed
  which is not very comprehensible)
- instead, don't show any output (this is not ideal since running a
  command in recovery mode does not have the same output as running it the
  regular way; instead the Client.safely_run() interface should be
  called)
