Value Statement

When dealing with templatizing kube resources, such as is done with PolicyGenerator there is often cause to generate dynamic resource names. when generating dynamic resource names you always have to be concerned about exceeding the 63 char limit for resource names. the way this problem is solved in the helm world is by using the `trunc` and `trimAll` functions such as:
{{}}
name: '{{ printf "%s-%s" myvar "my-post-fix" | trunc 63 | trimAll "" }}'
But we dont have access to the trunc and trimAll functions in ACM templates at the moment.

Using the list of funcitons currently avaialbe (https://access.redhat.com/documentation/en-us/red_hat_advanced_cluster_management_for_kubernetes/2.8/html-single/governance/index#open-source-community-functions) i can't even find a work around to achieve this same result, none of the string functions needed for dynamically cutting down a string are available.

This essentially means its impossible to safely have dynamic resource names when creating PolicyGenerator templates because you run the risk of exceeding the 63 char limit (as i found out the hard way at a client).
