[FEATURE] Separate model deployment pipeline from multi-acc Abalone/XGBoost template

[kukushking]

Describe the solution you'd like
Basic multi-account template in sagemaker-templates-service-catalog module along with training Abalone with XGBoost has an example CICD pipeline (CodePipeline) to deploy an endpoint to dev, pre-prod, and prod. Separate the concerns and move the CICD into a) separate template OR b) separate module.
