Own valid or self signed SSL certificate for custom domains and the main sub-domain

Is your feature request related to a problem? Please describe.
Yes, I am using the self-hosted version of netbird, and none of my domains has an SSL Cert so it is impossible to open https:// links in secured browsers.

Describe the solution you’d like
It would be great that we can import a wildcard certificate which we purchased somewhere else so that we can have valid certs for our domains. Letsencrypt and its limitations does not make it easy to achieve this. As we might need to geberate a new certificate with LetsEnc. which will cause our domain to be blacklisted for sometime.

Describe alternatives you’ve considered
With netbird, I do not see any alternatives and this function should be implemented in the core.
