LDAP dynamic Bind DN

[2union]

Allows to take username and password to Bind DN from form. Username should be masked in parameter LDAP_BIND_DN.
e.g.
REDASH_LDAP_BIND_DN_DYNAMIC: 1
REDASH_LDAP_BIND_DN: "%(username)s@kontur"

Whats different in percy/redash? It's looks equal on screenshots.

Hi,

(This is a template message, but I mean every word of it. Also you're welcome to reply)

Thank you for making this contribution. While we couldn't bring it to completion and merge, it's still very much appreciated. 🙇

In the past year the Redash code base gone under massive updates: on the backend we moved to Python 3 & RQ instead of Celery and on the frontend we replaced Angular with React. It's very likely this makes this PR irrelevant without significant changes. :-(

I'm closing this PR now. But if you're still interested in making it happen, let me know and I will reopen.

Thanks.
