Flag or Feature to automatically lowercase tag values

[away168]

Is your feature request related to a problem? Please describe.
In GCP there are rules where tag values needs to be in lowercase.

Describe the solution you'd like
Either, Terratag just knows to automatically change the values to lower case, or set a flag that will allow the user to decide when tags need to be all in lower case.

This flag should also be available as an Environment Variable setting.

Describe alternatives you've considered
In env0, we would need a custom flow, or support Bash 4.0 (to support variable manipulation like ${ENV0_PROJECT_NAME,,} (which turns the string to lowercase)

Additional context
n/a

@away168 - why not have the users just input their tags in lowercase?
I'm probably missing the context. If you can, please clarify. Thanks!
