Create script to build image and run container in dev mode

[olliesilvester]

For testing, we should create a convenience bash script which:

• builds the image if one doesn't exist already, with tag daq-config-server-dev
• runs the container, mounting the test data and dls_sw, and publishing ports. Probably something like podman run -v $(pwd)/tests/test_data:/workspaces/daq-config-server/tests/test_data:z -p 8555:8555 localhost/test-config-server
• The script should have an option to force rebuild the image

Acceptance Criteria

• Bash script described above is created
• I can run the bash script from my workstation and successfully talk to the config server at http://localhost:8555/docs
• Document how to test the repo using this bash script
