Lock/customize server setting when running a server using the AppImage file

Motivation

Running an OpenRA server using the AppImages file (link) is ridiculously simple and requires almost zero setup.
The basic parameters are all exposed and can be customized as in the sample script (link). However, it's not possible to specify custom server settings (link).

Proposed solution

It would be great to allow specifying those setting somehow.
One idea would be adding another parameter to provide a folder where the server can read the custom rules. E.g Server.SettingsOverrideFolder="/tmp/customOraSettings/"

./OpenRA-Red-Alert-x86_64.AppImage --server Server.Name="My Server" Server.ListenPort=1234 Server.SettingsOverrideFolder="/tmp/customOraSettings/"

Side effects

The server should read and apply the rules stored in the yaml files in the target folder.

Alternatives

Any other solution along these lines is fine -- I don't know the code enough to understand if the suggested solution is reasonably simple or not 😁

Start with launch-dedicated.sh and the AppImage server invocation documented in the linked wiki pages, then trace how the --server arguments are handled. Determine how custom YAML rules in a supplied folder should be discovered and applied, and define tests or a documented server run that demonstrates the settings are locked and active.
