AddAuthFlags adds the flags needed for authenticating to Service Bus.

ConstantlyUpdateQueue updates queue, changing the MaxDeliveryCount properly between 11 and 10, every `updateInterval` This will cause Service Bus to issue force-detaches to our links, allowing us to exercise our recovery logic.

LoadEnvironment loads an .env file.

MustCreateAutoDeletingQueue creates a queue that will auto-delete 10 minutes after activity has ceased.

NewCtrlCContext creates a context that cancels if the user hits ctrl+c.

TrackDuration tracks durations (as a metric), using the initial call to TrackDuration as the start.

TrackError tracks an error (using the AppInsights exceptions table).

TrackMetric tracks metric and respects any included baggage in the context.

these metrics are specific to stress tests and wouldn't be in customer code.

StressContext holds onto some common useful state for stress tests, including some simple stats tracking, a telemetry client and a context that represents the lifetime of the test itself (and will be cancelled if the user quits out of the stress).

TelemetryClientWrapper is a wrapper for telemetry client, once we get that phased back in.

TrackingReceiver reports metrics and errors automatically for its methods.

TrackingSender reports metrics and errors automatically for its methods.
