• I had searched in the issues and found no similar feature requirement.

Description

prepare a way to install the dependencies and build a custom image for users.

Use case

For a dedicated cluster to run a specific workload, user normally won't use job level runtime. Instead, they expect the cluster have dependencies installed directly and they are able to kick off the job immediately.

In that case, we need to create the ray cluster with preinstall dependencies.
User can definitely run Dockerfile by their own but it's not easy for platform owner to share the images and index the dependencies.

Let's implement this in a managed way
