feat: use uwsgi with http only

[david-kn]

Fixes: #519

To have an option to disable HTTPS communication within uWSGi.

Security of HTTPS can be handled by ingress which terminates TLS traffic and I find this useful / actually necessary when running in Kubernetes with only read-only filesystem that disallow processes to touch nautobot.crt and nautobot.key files defined within uwsgi.ini and cause an error during deployment (current state).

Of course other option is to enable nginx sidecar with nautobot but I think this could be useful for some scenarios.

Tried to update also docs and validation scheme which impacted quite many other lines...

Thanks a lot for the PR! I think it makes total sense.
Is it possible to also change nautobot-deployment.yaml template so we don't expose unnecessary ports?

Happy to contribute :-)

Thanks for your proposals.

I think so ;-) I'll try to take a look at it how it is connected there...

Put condition around exposing 8443 port.

Please, take a look if it meet your standards and approach.
