Add ignore validation flag while registering model & improve logging

[VipulMascarenhas]

Description

Mistral has released some of their models in the Mistral format where you get one consolidated.safetensors and a params.json , and there is no config.json file. We still want users to proceed with model registration since the current set up restricts user to proceed.

This PR adds a input check --ignore-model-artifact-check that will not throw an error during registration when config.json is not in the model artifacts.

Also, some improvements have been made:

• get_model_files() API will include .safetensors file names along with config.json. This ensures that the model file list is not empty when config.json is not present. This applies to files read both from Object Storage and HF repo.
• For HF models, telemetry name is set as HF model name.
• There was a validation added to check if model_type attribute from custom metadata matches the one in config.json. The metadata in service models don't have this field, hence any exception thrown was just ignored. We now log the details, and can update the code to throw an error when this field is added in all verified models.

In addition to this:
This PR adds additional logging statements in the CRUD operations for model, deployment, finetuning and evaluation operations in AI Quick Actions. In addition to this, the PR also covers the following:

• base_handler has been updated to log request id in the error logs.

Testing

Register via HuggingFace

Scenario 1: Model has config.json file, user can proceed with registration.

ads aqua model register --model google/gemma-2-2b --os_path oci://<bucket_name>@<namespace>/prefix/ --download_from_hf True --compartment_id $PROJECT_COMPARTMENT_OCID --inference_container odsc-tgi-serving

Scenario 2: Model has no config.json, but is supported by vLLM. Validation does not allow registration to proceed.

ads aqua model register --model mistralai/Pixtral-12B-Base-2409 --os_path --os_path oci://<bucket_name>@<namespace>/prefix/ --download_from_hf True --compartment_id $PROJECT_COMPARTMENT_OCID  

Scenario 3: Model has no config.json, but with --ignore_model_artifact_check True parameter can proceed with registration.

ads aqua model register --model mistralai/Pixtral-12B-Base-2409 --os_path --os_path oci://<bucket_name>@<namespace>/prefix/ --download_from_hf True --compartment_id $PROJECT_COMPARTMENT_OCID --inference_container odsc-vllm-serving --ignore_model_artifact_check True

Register via Object Storage

Scenario 4: Model comes from OSS and the path is correct. Validation says that there is no config.json file.

ads aqua model register --model mistralai/Pixtral-12B-Base-2409-from-OSS --os_path oci://<bucket_name>@<namespace>/prefix/ --download_from_hf False --compartment_id $PROJECT_COMPARTMENT_OCID --inference_container odsc-vllm-serving

Scenario 5: Model comes from OSS and the path is correct, and we use the override flag. Registration is allowed to proceed.

ads aqua model register --model mistralai/Pixtral-12B-Base-2409-from-OSS --os_path oci://<bucket_name>@<namespace>/prefix/ --download_from_hf False --compartment_id $PROJECT_COMPARTMENT_OCID --inference_container odsc-vllm-serving --ignore_model_artifact_check True
