[AIRFLOW-1813] Bug SSH Operator empty buffer
The SSH Operator will throw an empty "SSH operator
error" when running
commands that do not immediately log something to
the terminal. This is
due to a call to stdout.channel.recv when the
channel currently has a
0-size buffer, either because the command has not
yet logged anything,
or never will (e.g. sleep 5)
Make code PEP8 compliant
