Remove legacy non-blueapi code #1532
Description
When hyperion is finally fully migrated to blueapi, we will be able to remove the following code:
- Support for legacy GDA mode aka
GDARunner, launcher shell scripts support for the same - Support for the InProcessRunner, launcher code for the same
- hard-coded utility functions for loading i03 beamline and plans, since this is all now done via configuration
- Legacy REST API server code aka
create_app - Plan registry
- Legacy logging configuration
- Any other things we can think of
We can also tidy up the legacy composite factory methods since these are now all invoked by blueapi
Acceptance Criteria
- All the legacy cruft is GONE
