Function App access restrictions prevent faz-auth-scheduler to call the faz-auth-handler from within the same function app

[JaydenLiang]

it needs to add one rule in the function app > networking > access restrictions with the following settings to allow for calls within the same function app.

Rule:
priority: any number
Name: any
Source: AzureCloud // <-- very important

solution:
the template should create such rule by default.
