Adds the basic for harness embedded mode:
- Harness dedicated router with custom APIHandler
- Inline Space Creation
- Client for Account/Org/Project
- Bootstrap (Allows for automated creation of admin user and gitness service (used for all platform required ops))
- Inline harness service principal creation
- Ignore flag for ACL.
Preparing the support for harness specific API router + http handler, which allows us to have complete control over the rest api naming and functionality, without having to do complex path rewrites or request / reponse rewrites inline.
