az vm auto-shutdown not properly supported in az interactive and the --email options are ignored when specified

### **This is autogenerated. Please review and update as needed.**

## Describe the bug

**az vm auto-shutdown**
``
The az interactive mode does not recognize auto-shutdown as a valid command while typing the command line, but does run the command. However, the command ignores all forms of --email parameters (xxx@myco.com -or- aaa@myco.com;bbb@myco.com - regardless of quoting. The command runs and when you look at the portal, the notifications are off and the email setting is empty.
****

## To Reproduce:
Steps to reproduce the behavior. Note that argument values have been redacted, as they may contain sensitive information.
Just run az interactive and enter az vm auto-shutdown and you will not see auto-shutdown as an option.
Use the --email setting and once the command runs, the returned JSON will show the email address as null.

## Expected Behavior
az interactive should show auto-shutdown as a subcommand of vm.
az vm auto-shutdown should properly process the --email option settings
