support custom code for Hugging Face SageMaker model deployment

[krokoko]

Describe the feature

In some cases, the user needs to provide custom logic to deploy a HF model to a SG endpoint:

• overwrite/add dependencies to the existing DLC
• add custom inference script to manage inference requests
  In those cases, the user needs to use a notebook instance, SG Studio or a local environment to
  This step could be managed by the construct

Use Case

Avoid context switching and deploy more models directly through CDK

Proposed Solution

Add a new optional property customCode pointing to a location (local or S3) containing the custom logic of the user. If provided, the construct would run a CodeBuild step to:

• pull model artifacts from HF to an S3 location
• add user's custom logic
• deploy the model from the new S3 location
