Make sure ssh retries on paramiko.SSHException

We are occasionally seeing paramiko raise a SSHException which is
causing tempest to fail out, but on a constrained devstack environment
its possible that there are network or other performance issues, so we
want to keep retrying on an SSHException just like we retry on a
paramiko.AuthenticationException.

Attempt at Closes-Bug: #1253896
