Enable Authorization AAF Filter programmatically

Enable Authorization AAF Filter programmatically

The intent is to reduce configuration options and
automatically set up the authorization filter
(that will complement the authentication filter
that the policy-endpoints common framework automatically
provides).

Previously to enable the AAF authorization filter,
it will need the configuration had to kept track of
AAF flag, and the "filterClasses" property configuration,
make a bit more difficult to keep them sync, and easily
turn on/off AAF.
