Feature Overview:

The Customer would like to have all sprig functions with GRC policies.

For example:

https://masterminds.github.io/sprig/date.html

Perhaps other functions are missing as well, They'd like to use the full sprig suite.

https://docs.redhat.com/en/documentation/red_hat_advanced_cluster_management_for_kubernetes/2.12/html-single/governance/index#template_function_descriptions

For now they were able to achieve the date using this:

hub (now.Sub (toDate "2006-1-2T15:04:05Z" (fromConfigMap "acm-policies" "etcd-backup" "backup_date"))).String hub

But they are interested in having all the sprig functions anyways.
