Sphinx-ify QuantumPluginBaseV2 docstrings

The quantum.quantum_plugin_base_v2 module had some good docstrings,
but there was no corresponding sphinx code that would generate
docs from them. There were also some syntax issues with the
sphinx markup in the docstrings.

This change adds sphinx directives so these docs will be auto-
generated. It also modifies the docstrings in the QuantumPluginBaseV2
methods so they are parsed by the Sphinx documentation generator
without any errors.

If this patch is accepted, a "Plugin API" link to these docs
will appear at

http://docs.openstack.org/developer/quantum/

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.
