✨ Allow to configure registry mirror

[wingyplus]

What are you trying to do?

I would like to find the way to configure the registry mirror in simple way rather than managing the engine manually. So it would be great if the action allows us to define registry mirror or engine configuration over the action config and start the engine for us.

Why is this important to you?

In our CI, we have no docker hub user to login to docker.io but need to pull through registry mirror.

How are you currently working around this?

We're starting the engine with the registry mirror configuration before running the pipeline.
