Expected Behaviour

If the appinsights resourceazurerm_application_insights.example already has an api-key configured which is not meant to be managed by the current terraform state the resource azurerm_application_insights_api_key.read_telemetry should just ignore that existing key and manage the key described in the tf resource without issues.

Actual Behaviour

If there is already a key present which is not meant to be managed by the current terraform state the resource provider azurerm_application_insights_api_key ends up in an infinite loop unable to exit until the terraform timeout of that resource is reached. It is not possible to add another key as long the unmanaged one is existing.

Steps to Reproduce

Create an API Key in appinsights manually (name it differently than the one in the attached configuration)
Run the given configuration
