Add ability to query SageMaker Endpoints

[benglerHIG]

We need the ability to query all the SageMaker Endpoints running in all accounts in our Org. Currently SageMaker Endpoints are not available in the Config aggregator and advanced query section.

Running a query such as the below returns no results and this should display all SageMaker Endpoints:
SELECT
resourceId
WHERE
resourceType LIKE 'AWS::SageMaker%'

It would be helpful to have other SageMaker resources available to query in Config such as Notebooks, but Endpoints are currently the critical resource we need to be able to query.

We are actively working to add support for the SageMaker resource types in Advanced Query.
