Use lookup to create CIIP/GGIRCS/CIF database credentials automatically

[dleard]

The secrets that contain the CIIP/GGIRCS/CIF db credentials (used in the cron-db-pass template) currently need to be manually created in the metabase namespace. We could create them automatically with a lookup in the secrets template. There is an example of doing this in CIF where we are retrieving the GGIRCS db credentials via a lookup here: https://github.com/bcgov/cas-cif/blob/develop/chart/cas-cif/templates/secret.yaml
