org.opendaylight.aaa.sts.TokenAuthFilter is utilized as a restconf
JAX-RS filter. If TokenAuthFilter class is not loaded prior to
starting the sal_rest_connector, there is a chance that the Class
is not found, resulting in a loading race condition. This patch
includes code to specifically import the AAA sts package prior to
creating the sal_rest_connector service.
