How to use the azure keyvault secrets provider addon?

Hi all,

With the recent releases of the AzureRM provider which enable the azure_keyvault_secrets_provider addon, I am unable to find any examples of how to use it. While I have enabled the addon, created a keyvault in azure, I am a bit stuck as how else to proceed. I triued having a look at the examples folder in the repository and could not find an example of how this is used.

Any ideas would be helpful.
