Small addition!
My coworkers and I use this tool for quickly fetching a relevant list of parameters for a given application in a given AWS account. We need to quickly create run configurations to test different applications without having to manually go to the AWS console to copy and format each parameter individually.
This tool already speeds up the work but still requires us to do some tweaking of the format to make it work for our needs.
Adding this optional flag allows us to use this tool to facilitate this additional use case for this app.
Adding this flag is not a breaking change. It is an optional flag, and by default it is set to false, so no changes will occur if users continue to use this app as they have done in the past, even when they update to this version.
Users desiring this added feature will be able to use the feature by simply using the `--env-format` or `-f` flag in conjunction with their normal usage of `ls -v <prefix>`, so the final command can be as simple as something like this: `awsparams ls -vf <prefix>`.
