I forgot my password. How do I log in?

[adivekar-utexas]

Bug description

I have forgotten my JupyterHub password, and now I cannot login.

Expected behaviour

There should be a "forgot password" page, or some way for an admin to reset a user's password.

Actual behaviour

I cannot log in.

How to reproduce

1. Set a password.
2. Do not remember the password.
