[Bugfix][Feature Request] Add support for docker networking hostnames

[Letgamer]

At the moment it is not possible to update the tunnel config to point to a docker hostname.

Assume the following docker-compose.yaml:

services:
  crafty:
    image: registry.gitlab.com/crafty-controller/crafty-4:latest
    container_name: crafty
    restart: always
    networks:
      - crafty
  playit:
    container_name: playit
    image: ghcr.io/playit-cloud/playit-agent:latest
    restart: always
    environment:
      SECRET_KEY: "${SECRET_KEY}"
    networks:
      - crafty
networks:
  crafty:

To get this to work in you have to set the tunnel to Local Address: crafty and Local Port: 25565
But it is not possible to set the Local Address as a hostname, only IPs are possible

Workaround:

services:
  crafty:
    image: registry.gitlab.com/crafty-controller/crafty-4:latest
    container_name: crafty
    restart: always
    networks:
      crafty:
        ipv4_address: '10.1.0.100'
  playit:
    container_name: playit
    image: ghcr.io/playit-cloud/playit-agent:latest
    restart: always
    environment:
      SECRET_KEY: "${SECRET_KEY}"
    networks:
      - crafty
networks:
  crafty:
    driver: bridge
    ipam:
      config:
        - subnet: 10.1.0.0/16

By giving the container a 'static' IP it is possible to setup the Tunnel via the IP
But this requires more configuration and doesn't look clean
