[Feature Request] New az self-test since az self-test is deprecated and will be removed in a coming release

**Related command**

az self-test is used for testing if the az package is functional downstream in NixOS/Nixpkgs.

We would like to know if there is a new command that will replace this one in new releases ?

**Is your feature request related to a problem? Please describe.**

An azure cli command to self-test should be created for easily testing if packaging/compiling was successful for all the az-cli sub commands.

**Describe the solution you'd like**

A new az self-test command or alternative.

**Describe alternatives you've considered**

Just using the current az self-test is what we're doing right now.
