Feature request: Update Multiplayer Server Endpoint on Redirection

[touhidurrr]

This behaviour includes:

1. If host.example.com/isalive redirects to any url that ends with /isalive than replace multiplayerServerUrl with part of the url before /isalive

    example:
        redirect: example.com/isalive -> example.com/api/isalive
        new url to replace with: example.com/api
   

2. Similarly replace multiplayerServerUrl for hostname/files/:filename too

3. Don't replace if url doesn’t ends with same path. Eg. /isalive or /files/:fileName

4. Don't allow replacing if fileName doesn’t match.

This will allow community server owners to change their hostname easily without negatively affecting players for special circumstances.
