Split out orchestration

[julianstirling]

In this PR we are splitting out the generic parts of the orchestration and server into a new generic repository called CadOrchestrator

• [x] Move generic orchestration code to new repo
• [x] Move server to new repo
• [x] Modify code to run as before
• [x] Move generate.py functionality into cadorchestrator repo
• [x] Create generic way to specify the configuration class (or avoid need for it entirely)
• [x] Create generic way to specify configuration options to show in server and implement
• [x] Create generic way to specify server UI options (Text, CSS, Logos) and implement
• [x] Move nimble specific assembly configuration back to this repo

Closes #63, closes #72

Hi @jmwright

This is the first pass at splitting out most of the orchestration. There is more generalisation to do. And there are especially improvements for how we specify assemblies and sub-assemblies.

As much ass possible has been moved into a new settings file CadOrchestration.yml. There is also an "OrchestratorConfigOptions.json" that sets what the server asks. This has to be generated. Currently this is a bit ad hoc, but to improve it I think we really need to move to a framework for the server.

Anyway we are back to feature parity with where we were at the start of the merge. I think having the CadOrchestrator will sharpen the mind to trying to make things less specific to the nimble.

Now we have a first version, I will start to do Merge requests on the Cad Orchestrator repository too.

Testing this branch.

The CI tests the static generation generate.md has been updated with new methods.

For the server you should be able to:

• Checkout this branch, and stay in the root directory of the nimble repo
• run pip install -e . to install everything
• run gen_nimble_conf_options to generate the correct config options for the server to display
• run cadorchestrator serve
• navigate to http://127.0.0.1:8000/ to see the configuration server.
