azurerm_application_insights - retention_in_days defaults to 90

[hbuckle]

The current resource is not idempotent, it seems Azure now sets this to 90 by default

resource "azurerm_application_insights" "test" {
  name                = "test"
  location            = "uksouth"
  resource_group_name = "test"
  application_type    = "web"
}
