[PIPE2D-712] Make 'init' block optional in generateCommands

Relates — Thu, 4 Mar 2021 18:53:28 +0000

generateCommands.py currently requires an init block in the YAML file. This makes sense for the integration test and weekly, but not for steady state processing. Make the init block optional.

Without an init block:
