qa: test_rbd_wnbd.py - disable PS progress bar

This test uses certain PS commands that attempt to display
a progress bar. However, this can cause issues when invoked
remotely (e.g. by the jenkins job).

For this reason, we're defining a helper (ps_execute) that runs
PS commands, disabling the progress bars and enabling the non
interactive mode.
