Draft: add resource limits, add integration test for resource limits

1. Add new platform properties for memory-limit, cpu-time, unixUID, and unixGID
2. Add parsing and error handling logic for handling arguments for these new properties
3. Add a new integration test setup (new Python script that creates a new action, and new Dockerfiles to set up the test)
4. Add unit tests for the parsing of memory-limit and cpu-time properties
