Update git submodules

* Update docs/submodules/aaf/authz.git from branch 'master'
  to 40fad64132a671731e37ce97911a03db72ff7ecf
  - Fix: AAF timing issues

    We wait until the cassandra DB comes up and listen on TCP 9042
    before running any cqlsh commands. Also we increse cqlsh
    --request-timeout to 60 seconds and in order to prevent
    coordinator write timeouts we increase write_request_
    timeout_in_ms to 20 seconds. So that Cassandra DB comes up in
    all different setpups without any failures.
