creating the downstreamParameterized build step took awhile to figure out .. also, how to BLOCK progress while calling a downstream job .. what's nice is we can manage all of this here and it will update the jobs when we make a change .. so how we change branches on a regular basis for an env, manage that here and commit and the HC room will be updated whenever we make a change .. can also create a nice hal command to show the contents of this so we can see what is enabled/disabled/etc ..
