What does this MR do?

Support deploying Sidekiq Jobprocessor

Template and deploy a Sidekiq jobprocessor.

• The Jobprocessor/sidekiq task does:
  1. Calculate a config checksum.
  2. Template the sidekiq deployment.
  3. Apply the sidekiq deployment.
• The workload uses the same configuration/secrets as the webservice workloads.
• The controller currently does not check the sidekiq status.
