More examples for **az cli resource**

**Is your feature request related to a problem? Please describe.**
When using **az cli resource** it's pretty difficult to format the command properly, especially in case of resources that need a lot of properties.
It requires either using Azure REST API docs or digging in the documentation.

**Describe the solution you'd like**
My suggestion is to provide more sample in a separate repo.
I have created a sample repository of processed examples here:

https://github.com/zikalino/azure-cli-resource-examples

These examples are autogenerated using autorest directly from Azure REST API specs.
We could make it more official and that would provide great value for users.

In addition it could lead to great improvement to the examples themselves.

**Describe alternatives you've considered**
- visual studio code extension
