[FEATURE] Support other model types in CreateAlertTool and CreateAnomalyDetectorTool

[yuye-aws]

Is your feature request related to a problem?
CreateAlertTool and CreateAnomalyDetectorTool only supports Claude and OpenAI as the model types. We need to support more model types. Just like: https://opensearch.org/docs/latest/ml-commons-plugin/remote-models/connectors/.

What solution would you like?
Refer to the connector and model interface in ml commons. Model interface document: https://opensearch.org/docs/latest/ml-commons-plugin/api/model-apis/register-model/.

What alternatives have you considered?
I'll look into the current implementation of connector and model interface. We'll reach a conclusion after discussing with tool owner @gaobinlong and @qianheng-aws.

Do you have any additional context?
These 2 tools needs model_type parameter due to prompt customization.

I suggest we can make this a flexible implementation which can adapt to more and more models automatically w/o blocking user's integration.

Agreed. The CreateAnomalyDetectorTool now supports every model_type with the prompt parameter. The CreateAlertTool can follow the existing implementation of CreateAnomalyDetectorTool.

Hi @gaobinlong ! Do you think the comment also makes sense for CreateAnomalyDetectorTool? If so, can you create a small PR to fix it?
