mysqlfabric prints a python-like, json-like, ... output as result.

The output itself looks like it would be parsable, but it isn't.

How to repeat:
jan@jan-t420:~/.local/bin$ ./mysqlfabric group create group_id-global
Procedure :
{ uuid        = 01cbab7a-8dc8-4585-9629-fd3d15892c4f,
  finished    = True,
  success     = True,
  return      = True,
  activities  =

Suggested fix:

* make the output parsable: JSON, YAML, ... or
* hide the output on success and use exit-code 0 and use a human-focused error-msg in case of error to stderr using a non-zero exit-code.

Bundle with the fix. In this case I have used json to send the string from the server to the client.

Use the return value from the command as the exit code

Fixed as of the upcoming MySQL Fabric 1.6.1 release, and here's the changelog entry:

"mysqlfabric" would print a JSON-like output as a result, but this was
potentially confusing as it was not JSON. Valid JSON is now used.

Thank you for the bug report.
