Bug Description

SSHClient in fuel-devops uses 'print' function to verbose the output of the execution a remote command.

But the output of 'print' function can be in wrong order towards the logger.info output.

Example of the current output (pay attention to the strings with "Executing command:...". The command with "apt-get-update" should be in the step #2; all the output before it - from the step #1): http://paste.openstack.org/show/597506/

This is how it is expected: http://paste.openstack.org/show/597507/

In the first example above, steps headers "[ Install ...]" are shown with logger.info() method, all the rest - with print() function.

In the second example, print() is also replaced with logger.info() and looks fine.

    Replace 'print' with 'logger.info()' in command executors

    To avoid wrong ordering of the output lines, use the same output
    method logger.info() in SSHClient and Subprocess from helpers.

    - use logger.info and logger.error in case 'verbose=True'
    - use logger.debug for stdout and stderr in case 'verbose=False'
