Problem Description:
Some plugins, like SAML and LDAP require additional libraries beyond django-social-auth or what we would normally include in django-ansible-base.

We would like to research a way to have the authenticator plugins specify their own requirements and have django-ansible-base be able to pickup these requirements and append them to its own requirements.

User Story
As an authenticator_plugin developer I need a way to add additional requirements into django-ansible-base with out having to modify django-ansible-base directly.
