Add core:Datalist, documentation and CLI client based on OpenAPI description

[trkks]

Additions include:

• Service/"module" on orchestrator named core:Datalist that gets added at startup
  • Stores and queries input in a list
  • Uses a module init-function that a supervisor (or the orchestrator itself in this case) can call at deployment time (sets up database collection)
• OpenAPI description for orchestrator (though the various request errors are not regarded)
• Command line interface client based on the API description as an alternative for web GUI
  • Uses Typescript with openapi-typescript-codegen for client code generation and commander.js for the CLI
  • Container for running it
• Example script icwe23-demo.sh for how the CLI can be used
• A test Wasm-module abc that represents different ways of inputs and outputs
• More documentation of orchestrator with diagrams and links to implementation
• Remove unnecessary mock-classes (database and device-scanner)

This PR is ready to go on my part. There is a related branch on the modules with description.json files for use with the CLI, but at the moment only for the camera and onnx-inference modules.
