Add more Golang Template functions to template parser

[posorio88]

Currently is very difficult to implement basic behaviors with custom templates using just "split" and "trim" functions exported in "internal/configs/version1/template_helper.go". Whenever a list needs to be generated within the template or similar, the code gets unreadable very quickly.

Can we get more functions (much like the ones present in helm or sprig)?

Hi @posorio88 thanks for reporting!

Be sure to check out the docs while you wait for a human to take a look at this 🙂

Cheers!

Hi @posorio88 we've added a few more helper functions since this issue has been created.
You can find the list of them here: https://docs.nginx.com/nginx-ingress-controller/configuration/ingress-resources/custom-annotations/#helper-functions

Can you please let us know if there are any more you feel should be included? We are always looking to add more useful functions here that help improve development around our templates.
