feat(security): add option to use Certbot

[AnonymousWP]

Expected feature

As some reNgine-ng instances are publicly accessible, we may want to implement a Certbot-like solution for automatically obtaining and assigning a TLS certificate. I'm thinking about the following:

Ask user whether it wants a certificate during installation: if yes, pull Certbot image. If not, don't use Certbot and use self-signed certificate.

Alternative solutions

If it's not possible, write manual about how to accomplish this manually.

Anything else?
