Issues:
Fixes #894

Problem:Ocata Development LBaaSv2 driver issue with ML2 portbinding extension

Analysis:As neutron.extensions.portbindings.EXTENDED_NEUTRON_CONST_2_0 dicti
-onar is absent in Ocata, i commented out the lines wherever the
attribute "binding:capabilities" was encountered in the code.

Tests:Created and ran the test "f5lbaasdriver/v2/bigip/test/test_plugin_rpc.py"
