ml2 extension manager doesn't pass db entry to entend_xxx_dict

[Isaku Yamahata]

extension driver isn't passed dbentry to extension result dict
extend_{network, subnet, port}_dict() aren't passed db entry, but only result dict. In order to extend the result dict, db entry is necessary.

Supplement:

I hit this issue during I'm trying to convert portbindings extension into extension driver.
I'd like to reuse extend_port_dict_binding (or _extend_port_dict_binding_host).

    Passes the plugin context variable in the ML2 Extension Driver API

    Many neutron extensions(like portsecurity) use the plugin_context
    variable instead of just the database session. This change
    modifies the extension driver api to pass the plugin_context

    Change request also modifies the extend_XXX resource api to use the
    respective data model(network/subnet/port) passed to it.
