Non-Alpha-Numeric User Groups

**Describe the solution you'd like**
A clear and concise description of what you want to happen.
When I go to create user groups it is requiring me to use alpha-numeric names, I know this is not a requirement through the console, and would like to be able to use non-alpha-numeric names through CLI as well.
**Describe alternatives you've considered**
I'm wondering if I go into the generated code after running the CLI if I can just change the name to be non-alpha-numeric? Would that work or would that run into issues down the push process?

The issue names no files, tests, or entry points. Start by reproducing user-group creation through the CLI and comparing its name validation with the AWS console behavior. Done means the CLI accepts non-alphanumeric group names safely, with coverage for creation and deployment if the project identifies relevant tests.
