Remove shared-secrets chart. Move jobs to chart root.
Summary
We've encountered several places where it's difficult for the shared secrets chart to make decisions on what secrets to populate, because it doesn't have access to the root chart's values. Meaning it can only made decisions based on values that are in globals.
The solution is to move the jobs/templates from the shared-secrets chart into the root chart. So that they have the root chart context.
