Security group list command tries to get a project list and
this may fail with a multitude of exceptions including but
not limited to 401, 404, ConnectionRefused and EndpointNotFound.
Rather than try to capture every possibility, this patch just
catches the base class.  Converting project ids to names is
less important than having a working security group list command.

This allows the server delete command to wait for the server to be
deleted (obviously).

The wait method is the same model that Tempest uses, i.e. wait for a 404
on server GET (successful deletion), fail if the server went to ERROR
status, or fail if a timeout is reached.  The default timeout of 300
seconds is also what Tempest uses.

By default the --dst-port value is set to None when no --dst-port
argument is provided. By making the default value (0, 0), this allows
novaclient to proceed without any error.

--description is optional in our CLI but the server requires it to be
non-empty.  Set a default value of the given name.
