add support for overriding sagemaker model deployment

[samhita-alla]

Tracking issue

Why are the changes needed?

This can be useful for deleting an existing deployment before creating a new one if there's already one in place.

What changes were proposed in this pull request?

Add an override parameter to the create_sagemaker_deployment function to delete an existing deployment before creating a new one. It'd be more useful to check if the endpoint, endpoint configuration, and model exist before deletion to avoid Could not find xxx errors. However, implementing conditional checks in the workflow isn't possible with imperative workflows.

Currently, this option can be used to delete all three entities before creating a deployment, given that they exist.

How was this patch tested?

I think a complementary approach is to create a task SagemakerEndpointExists so that users can compose a workflow themselves with the conditional:

@workflow
def wf():
    (
        if_(SagemakerEndpointExists(name="my-model")
        .then_(create_endpoint(..., override=True))  # delete then create
        .else(create_endpoint(...))  # create
    )

I guess once conditionals in imperative workflows is implemented this pattern wouldn't be necessary

@cosmicBboy i think we can create a workflow to handle this case as we need to use the list API to check if the endpoint's available. i'll work on it.
