#1067: Refactored mozart.tf so that deploy_pges.py and deploy_pcm_and…

…_pges run in parallel. This saves 20 mins of deploymnt time on dev cluster: 1 hour and 15 mins to 54 mins

Purpose and Proposed Changes

• In mozart.tf pull out remote_execs that installs bach_ui and runs deploy_pges.py into its own null_resource: bach_and_deploy_pges to speed up deployment

Explanation

• The end result is that these two will run in parallel to other mozart terraform resources running, in particular deploy_pcm_and_pges This and deploy_pges.py are the two longest running resource when deploying Mozart and by allowing them to run in parallel, 20 mins is saves in deployment time: 1 hour and 15 mins to 54 mins on average.

Issues

• [New Feature]: Reduce OPERA PCM deployment time by breaking out and reducing dependencies in terraform files #1067

Testing

• Destroyed and deployed in my personal dev cluster twice. Both were successful and both took 54 mins to deploy (as opposed to 1:15 previously)
• Ran all major query, download, SCIFLO, and CNM-S jobs and they all succeeded.
• You can see lines like this now:
  module.common.null_resource.install_pcm_and_pges: Still creating... [16m30s elapsed]
module.common.null_resource.bach_and_deploy_pges: Still creating... [16m30s elapsed]
• And this is the final line output for deploying pges confirming that it was running in parallel and that it took 17 minutes
  module.common.null_resource.bach_and_deploy_pges: Creation complete after 17m14s [id=2647260127362677226]
module.common.null_resource.install_pcm_and_pges: Still creating... [17m20s elapsed]
