Configure project from code (api/PUT)

[amberrignell]

User story

As a developer configuring a Lightning project and writing my jobs in my code editor, I want to configure and deploy my changes to my Lightning instance through the command line, so that I don't have to make the changes manually through the UI.

Details

Create an API endpoint which, given a project.yaml and/or some files, can configure a project on lightning.

Implementation notes

Release notes

User acceptance criteria

• When I deploy a project which already exists in Lightning, it doesn't create a new one but rather updates the existing one.
• If my lightning instance and my project as code have a job expression with the same id but different values, the lightning instance's job expression gets update with the new job expression.
• When I deploy a project which is scheduled for deletion, I get an error. (moved to Consider blocking project update via API once its been marked for deletion #876 )

@amberrignell , user acceptance testing

1. update in place, yes

2. rewriting job code, yes

3. error when trying to deploy to project marked for deletion, not quite...

For this last one, let's discuss. It's a one-line change to make this throw an error, but I want to be double sure that this is the behaviour we want. See change here if we want it:
