  - Fix CADI Connection to Remote DNS AAF servers on proxied network

    Java CADI client code and web filter has been fixed to allow
    specification of a fixed hostname for connecting to AAF
    service and avoiding use of the AAF Locator service to bootstrap.
    The CADI code was also updated to avoid pre-resolving DNS in this
    scenario.  This fix is necessary to address use cases where the
    AAF servers live in a different network domain from the CADI
    client where the access point is through a proxied endpoint and
    the DNS name is unresolvable on the network where the CADI client
    code is executing.
