Delete returns successful even if the resource does not exist

Hello,

I have been noticing a pattern for most of the azure resources I have played around with, The "Delete" operation does not return an error when the resource does not exist, what is the rationale behind this design and if this is a bug? Here is an example below:

```
nishantkumar@SUPERNO-KTK3FNI ~ % az container list -g nishkumar-rg
[]
nishantkumar@SUPERNO-KTK3FNI ~ % az container delete -g nishkumar-rg -n random-container
Are you sure you want to perform this operation? (y/n): y
nishantkumar@SUPERNO-KTK3FNI ~ % az container delete -g nishkumar-rg -n random-container --debug

Start with the az container delete command and the DELETE request to the Microsoft.ContainerInstance containerGroups endpoint using api-version=2021-09-01. Compare the reported 204 response with the API specification and determine whether the behavior is intended; done means recording the expected behavior or identifying a concrete specification change.
