Azure App Configuration Health Check

[MarcelMichau]

What would you like to be added:

Support for Azure App Configuration

Why is this needed:

Azure App Configuration provides a central configuration store for applications. It would be nice to have a health check for App Configuration similar to Azure Key Vault.

I've attempted implementing an App Configuration health check package in this fork which is based heavily on the Key Vault health check. I didn't want to issue a PR unless this is something that would be of interest.

Keen to hear thoughts!

I definitely see a value in adding the new package for Azure app configuration similar to the existing Key vault. @MarcelMichau @sungam3r

I'm interested in a package for Azure App Configuration as well.
