[FEATURE] Add model registry feature in ml-commons OSD plugin

[wanglam]

Is your feature request related to a problem?

We are going to add the feature of Machine Learning Model Registry, where users can upload custom models. The model has fields such as name, description, tags, and metric, and users can view the specific information of the model on the details page. Users can upload multiple versions of models, and the models uploaded by users will be displayed in the model list. Users can load the model into the OpenSearch cluster for use.

What solution would you like?

We will call the ml-commons plug-in in OpenSearch to implement functions such as model uploading, browsing, searching, and loading.

What alternatives have you considered?
