Remove set -x from exporter scripts and htk s3 user script

This removes set -x from the templates for the user creation
scripts for the mariadb and postgresql user templates, and it
also removes the set -x from the helm-toolkit job for creating
s3 users. This prevents sensitive credentials from being
displayed to the console when these scripts are run
