Description

CLI can supply second parameter such as:

yarn container -shell [container-id] sh

This is supposed to launch sh instead of bash. This is not fully working yet in YARN-8778 patch and some organization of code clean up to support non-docker container in YARN-8962 making this change in YARN-8778 difficult. Hence, I file this as a separate sub-task to close the gap.
