Implements: #12267

Includes:

• basic driver
• config options to define domains and tokens
• minimalistic error handling in case there is no access token configured

Note: I had to make a change to the VcsDriver to address a PHPStan issue. This now surfaced more PHPStan issues. Happy to address, ignore or baseline them.

Sample composer.json

{
    "name": "acme/project",
    "version": "1.0",
    "repositories": [
        {"type": "vcs", "url":  "https://codeberg.org/glaubinix-acme/acme"}
    ],
    "require": {
        "glaubinix-acme/acme": "1.0"
    }
}
