[nikhil-sk]

Description

Adds following details to SageMaker endpoint deployment guide:

1. https://docs.aws.amazon.com/sagemaker/latest/dg/large-model-inference-hosting.html

(Option to set VolumeSizeInGB, ModelDataDownloadTimeoutInSeconds, ContainerStartupHealthCheckTimeoutInSeconds)

We could point to AWS docs (ideal) or mention these in our docs itself.

2. Another is to deploy uncompressed model: https://docs.aws.amazon.com/sagemaker/latest/dg/large-model-inference-uncompressed.html
