deprecate doa-kerberos by using setuptools optional dependencies

[Steve Martinelli]

The django-openstack-auth-kerberos project[1] should be deprecated and it's functionality should be collapsed into django-openstack-auth proper, by way of setuptool's optional dependencies.

Simply have a section in setup.cfg called 'kerberos' that installs the kerberos package, if a deployer wanted to install django-openstack-auth with kerberos, they would type something like... pip install django-openstack-auth[kerberos].

    deprecate the entire library

    the library is essentially unmaintained, no tests have been added
    since it's inception 1.5 years ago.

    we can move the functionality to django_openstack_auth proper
    using extras, or attic the entire library if no one is using it.
    either way, this is a step toward both of those outcomes.

    delete all files in the repo

    the project was barely maintained and will be retired. deleting all the
    file in the repo (with the exception of the README) is the next step to
    retiring the project completely.
