AAI-326 add scheduler/job queue to automated deployment

[marius-mather]

Description

AAI-326: add a container that runs the job scheduler to the automated CDK deployment. We can reuse the existing docker image for this, we just run it with a different command.

Changes

• Add a container to the deployment that runs the job queue/scheduler
• Increase CPU/memory for the service since we're running 2 containers now

Checklist

• I have commented my code, particularly in hard-to-understand areas
• I have added unit / integration tests that prove my fix is effective or that my feature works
• I have run all tests locally and they pass
• I have updated the documentation (if applicable)

How to Test Manually (if necessary)

Difficult to test locally as it requires access to AWS secrets etc. - probably need to merge this and check that the deployment succeeds in GitHub Actions.
