Description

traffic_analytics inside azurerm_network_watcher_flow_log currently defaults to a "traffic analytics processing interval" of 1 hour. The Azure portal allows setting this value to either 1 hour or 10 minutes.

The ARM template includes a parameter (trafficAnalyticsInterval) to set "The interval in minutes which would decide how frequently TA service should do flow analytics"

It would be useful to add this setting to the terraform provider.
