Add 404 retry on Instantiate

[amarbut24]

Hello,

We're using the Terraform resource azuread_application

When using this resource we're referencing a template via template_id and we're seeing intermittent errors

{"@level":"error","@message":"Error: Could not instantiate application from template","@module":"terraform.ui","@timestamp":"2024-05-08T02:43:41.520121Z","diagnostic":{"severity":"error","summary":"Could not instantiate application from template","detail":"ApplicationTemplatesClient.BaseClient.Post(): unexpected status 404 with OData error: NotFound: Graph call failed with httpCode=NotFound, errorCode=, errorMessage=, reason=Not Found.","address":"module.dummy-application.azuread_application.saml_application"

I'm wondering if its possible to add a RetryOn404ConsistencyFailureFunc to the post to help with this intermittent issue.
If this looks good/acceptable, what is the timeline to pushing this out to the Terraform Provider?

Hi @amarbut24, thanks for suggesting this change. This LGTM, I'll include it in the next version of the SDK and it should make it to the AzureAD provider within a few days.
