[Pulp-dev] Pulp 3: using JWT to request a JWT

tl;dr We should support only basic auth for 3.0 and implement JWT
authentication in 3.1+

We currently have 2 stories[0-1] related to JWT authentication that we
wanted to implement for 3.0. As @bmbouter, @daviddavis, and I tried to
groom them earlier today, we decided that we are not ready to commit to
using "djangorestframework-jwt" app for handling JWT authentication. This
app has some behaviors that we want to override and also comes with several
configuration options that we don't want to support long term. I am
proposing that we remove JWT authentication from the MVP and move it to the
3.1+ list. I'd like to

 - close issues 3163 and 3164
 - move JWT auth use cases from the MVP document[2] to the 3.1+
document[3].
 - add a story for removing "djangorestframework-jwt" from pulp 3.0
