Big Switch: keyerror on filtered get_ports call

[Kevin Benton]

If get_ports is called in the Big Switch plugin without 'id' being one of the included fields, _extend_port_dict_binding will fail with the following error.

Traceback (most recent call last):
  File "neutron/tests/unit/bigswitch/test_restproxy_plugin.py", line 87, in test_get_ports_no_id
    context.get_admin_context(), fields=['name'])
  File "neutron/plugins/bigswitch/plugin.py", line 715, in get_ports
    self._extend_port_dict_binding(context, port)
  File "neutron/plugins/bigswitch/plugin.py", line 361, in _extend_port_dict_binding
    hostid = porttracker_db.get_port_hostid(context, port['id'])
KeyError: 'id'

    Big Switch: Check for 'id' in port before lookup

    Check for the presence of the 'id' key before trying
    to do a lookup based on the value. This is necessary
    because a 'fields' param to get_port(s) may exclude
    the 'id' field before the host_id lookup.
