sagemaker: Make IEndpointConfig property of Endpoint optional

[petermeansrock]

Describe the feature

Even though explicitly defining an EndpointConfig resource allows for reusable configuration across endpoints, as discussed on the original Endpoint L2 construct PR, customers looking to deploy a single endpoint may find it easier to have the endpoint configuration encapsulated within the endpoint construct.

Please 👍 this issue to help with the prioritization of this feature.

Use Case

Customers may not want to have to define their own IEndpointConfig resource, instead relying on Endpoint to instantiate one for them (in the event they don't provide one on EndpointProps).

Proposed Solution

Add each of these members of EndpointConfigProps to EndpointProps as optional arguments (while making the existing IEndpointConfig prop value optional as well) while ensuring that the IEndpointConfig property and the new members are mutually exclusive.

In this scenario, it likely also make sense to include an addInstanceProductionVariant on Endpoint so that customers can mutate the backing EndpointConfig in the same manner as they could using their own instance (this does have the added bonus of returning an IEndpointInstanceProductionVariant instance from the method, eliminating the need for customers to look up the variant by name).
