add alternate configuration so "web" images (app.jar) can be loaded in docker

[pappde]

ISSUE

Here is a dev experience following the documentation:

1. setup docker
2. cbioportal repo: use docker to build "web-and-data" image (with loose files)
3. cbioportal-docker-compose repo: run "docker compose up"
4. observe works

If the dev wants to test with the "app.jar" image, which mirrors the actual production deployment, the steps would not work:

1. cbioportal repo: use docker to build "web" image (with loose files)
2. cbioportal-docker-compose repo: run "docker compose up"
3. observe error about PortalApplication missing in docker container log

FIX

This PR adds an alternate docker configuration (YML) that instead loads the image and executes the app.jar. So the user needs to do:

docker compose -f docker-compose.web.yml up

RELATED

Still need to update the cbioportal repo documentation. That will be a separate PR.

FURTHER WORK

Copy-pasting the docker-compose.yml is not very maintainable. There is probably much better solution to this that someone familiar with docker configurations can address.

For example, is the "command:" line really necessary, since each image has it's own Dockerfile that can define what should be executed? Is it only in place for the "rm servlet-api-2.5.jar" hack? Is that still necessary?

@pappde thanks for these fixes! Very helpful! Could you maybe move the yaml file under dev/ somewhere? Feels like this is bit more of an advanced use case

I think you can avoid copying some of the Docker Compose file by supplying multiple docker compose files with -f file1 -f file2. E.g. similar to how it is done for open-ports: docker compose -f docker-compose.yml -f open-ports.yml up. It only overrides the couple of fields that need to be changed. Hope that helps!
