📄 Description

Describe your changes

This PR adds the ability to provide custom SSL certificates to the signal service. Most of the code was adapted from management/cmd/management.go since it already offers the functionality I was looking to implement.

Two flags have been added, --cert-file and --cert-key, which accept a string pointing to a file path for the SSL certificate and key. When --letsencrypt-domain is set, these options are ignored.

This is my first try at go, so please let me know if anything needs refactored and fixed!

Issue ticket number and link

Along with https://github.com/netbirdio/dashboard/pull/399, closes #2242

Checklist

Is it a bug fix
Is a typo/documentation fix
Is a feature enhancement
It is a refactor
Created tests that fail without the change (if possible)
Extended the README / documentation, if necessary
