Need a way to override volumes-* and overrides-* within a project

[mike-potter]

Currently Docksal creates the docker-config files by piecing together files in the following order:

global stack-*.yml
project docksal.yml
project docksal-ENV.yml
global volumes-*.yml
global overrides-*.yml

(where "global" is the user's .docksal folder and "project" is the current project's .docksal folder)

The problem with this is there is no way for a project to override anything in the docksal "volumes" or "overrides" file. In my specific case I need to change the overrides-dd-bind.yml file for it to work with Orbstack. I'd rather not make a global change in my main docksal folder (which would get overwritten by a Docksal upgrade). I can't even define my own volumes-orb.yml stack within my local project.

I propose allowing a project to define a docksal-overrides.yml file (or something like that) which would be processed at the very end to allow projects to override ANYTHING coming from the Docksal stack when needed.
