[WIP] AGENT-1326: Add InternalReleaseImage templates generation during the bootstrap (with RenderContext)

[andfasano]

• What I did
  Enhances the machine-config-controller bootstrap command to add conditionally the InternalReleaseImage related templates (based on the presence on the InternalReleaseImage resource and if the related feature gate has been enabled)

• How to verify it
  Add the InternalReleaseImage resource in the bootstrap manifests dir (/etc/mcc/bootstrap) and enable the feature gate.

• Description for the changelog
  Add support for InternalReleaseImage resource

This would be easier to review if the refactoring to use RenderContext were in a separate commit from the changes to add IRI registry templates.
