Add support for Data Access Configuration for Azure redis

[ant0nsc]

Related command az redis

Is your feature request related to a problem? Please describe. I'm trying to set up an Azure redis cache using the CLI. I can do most things, but for the data access policies, I need to resort to the UI/Azure Portal, which is painful for many users

Describe the solution you'd like

• Add a user with Owner policy: az redis data-access add --user foo@bar.com --policy 'Data Owner'
• List all users, their access policies, and usernames: az redis data-access show
• Query the user ID of a specific user: az redis data-access show --user foo@bar.com

Describe alternatives you've considered There is no commandline alternative, I can only use the Azure portal
