Add InvalidExternalNetwork exception to display correct error

Fixes bug 1075089

The message in the BadRequest exception raised in file
quantum/tests/unit/test_l3_plugin.py is
being muted in the logfile  since the BadRequest is
catched and writes its own log message.

Add rollback for Cisco plugin update_port failure

Fixes bug 1174433

This fix adds a rollback of the OVS plugin update_port operation
following a failure to update the port in the Cisco Nexus sub-plugin.

Also, this fix removes an unneccessary call to the Nexus sub-plugin's
update_network method within the Cisco plugin model layer's
update_network method (as well as the associated argument setup).
The Nexus sub-plugin's update_network is a no-op, so there's no
need to call it.

Add extra details in BigSwitch config

Add some details to some of the BigSwitch configuration options.

The doc team will soon be generating documentation for configuration
options by extracting it directly from the source code help strings,
which is one of the motivations for adding this detail.
