Adding python-memcache to contrail-openstack-config dependency

contrail-config uses keystonemiddleware to authenticate with keystone.
keystonemiddleware has a dependency on memcache, but the dependency is
not defined in the upstream keystonemiddleware package.
Adding the dependency in contrail-openstack-config as the config node
needs memcache installed while using keystonemiddleware.
