Fix terra-daemon ServiceAccount issues

This merge request fixes #69 (closed)

This fully deletes all ServiceAccount references for the terra-daemon helm templates.

In my opinion, it would be better to keep all of the service account references removed in !455 (merged), and just disable the ServiceAccount creation in values.yaml. However, this merge request has been formed consistently with the complete removal of the serviceaccount.yaml file, which is referenced in several other files.
