Removing sprig from our dependencies - user feedback wanted on --profile-template template functions

[chrnorm]

Hi folks, as part of removing Granted's integration with Common Fate (see https://www.commonfate.io/blog/winding-down) I have stripped a bunch of third-party dependencies from Granted. I'd like to continue with this and continue to cut back on the number of third party dependencies that Granted uses.

One such dependency is sprig, which was added to common-fate/awsconfig to resolve #478. sprig allows functions like lower and replace to be used in our --profile-template flag in granted sso populate and granted sso generate, such as:

--profile-template '{{ .RoleName | lower }}/{{ .AccountName | lower }}'

I would like to remove sprig as a dependency and vendor the specific functions that folks need from the library. The current functions I'm thinking to vendor are:

• lower
• replace

I'd like feedback though from folks who are using other functions from sprig so that we can also vendor these, to avoid breaking your workflows.

If you're using these functions in --profile-template, please let me know which functions you're using below
