run_cmd[helper function]
Description
- Terragrunt's parser ends up parsing
terragrunt.hclfiles multiple times, which is normally harmless, but in the case of therun_cmdhelper function, which can execute arbitrary code with side effects, this could cause problems. Therefore, we now cacherun_cmdcalls based on the arguments passed to them so that they are only executed once.
