CIP-2003 update system tests to use multiple delay models
- added delay model config schema to support the delay models layout changes for CIP-2003 and SP-4061
- The delay models will be moved from delay_model_package.json into standalone files. For example: delay_models_package_1.json.txt
. Validation criteria mostly copied from criteria for delay_model_package.json. Each element of the models array is validated against the telescope model. - The delay_model_package.json schema will be renamed to "delay_model_config.json" and overhauled to a high-level summary
- The delay models will be moved from delay_model_package.json into standalone files. For example: delay_models_package_1.json.txt
- updated validation script
- tested locally - used the same files that i have in the system-tests branch for testing
