Description

TestDistributedShell has grown so large over time. It has 29 tests.
This is running the risk of exceeding 30 minutes limit for a single unit class.

• The implementation has lots of code redundancy.
• The Jira splits TestDistributedShell into three different unitTest for each TimeLineVersion: V1.0, 1.5, and 2.0
• Fixes the broken test testDSShellWithEnforceExecutionType
