Ingress support

[lociii]

First thanks for building this awesome addon.
Paperless rocks. Being able to effortlessly run it within my HA setup rocks even more!

It would be great to have paperless integrated in the sidebar with "automatic" login for easy access.
The feature is called Ingress.

Ingress is necessary for Nabu Casa... I would love to see this.

This is not something I am going to work on at the moment, however, feel free to open a PR for this.

Also, something to consider before exposing Paperless to the internet, even via Nabu Casa, is that you may be storing highly sensitive documents in Paperless. When exposing it to the internet there is always a risk of these documents leaking.

Though I think it might be more secure to expose it via Ingress than to expose it directly, as Home Assistant has more eyes on the code base, so if there is a vulnerability in the authentication it is more likely to get fixed.
