Python Host Template

[elliotcmorris]

What

Create a template project similar to the manager template.

Why

Our onboarding process for host writers has become an impediment for adoption. A host template gives good bang for the buck.

As it to improve docs, we also wanna

• Bring this into integrations.yml (along with the manager template really,) so it stays working
• Link to the templates prominently in onboarding adjacent docs.

Acceptance Criteria

• Make a host template repo similar to the manager template repo
• Extract/remove simpleresolver, extend it to add any missing functionality to match the manager template
• Show example of basic happy path CI using BAL, open for extension by user. Does not need to be full coverage, just an example.
• Ensure docs are well written, up to date, etc, similar to manager template.
• Repo should be "ready to go", so people can clone it, (its a template repo)
• Added to integrations.yml CI checks on core OpenAssetIO.
