RESOURCE_TYPE support

[evelyn-ys]

Why do you need this feature?

In cli, we may need RESOURCE_TYPE to manage multi-api resource for different profile. But auto generated code don't contain resource type info. https://github.com/Azure/azure-cli/blob/4bed6cca3ebb746d0f8bc2b44c75f0d0d2f7ed15/src/azure-cli/azure/cli/command_modules/storage/init.py#L13-L27

Describe the solution you'd like

Support generate cli commands with specified resource type.

Additional context

Existing examples:

• resource type in cli
• customize resource type in storage-preview extension
