Prebind warmup code.
Prebind warmup code. Used for warmup tasks that we want to run before we accept traffic.
The service is bound to a port and warmed up, announce health.
Give the application control over when to present to Mesos as being ready for traffic. When the method
warmupComplete()is invoked, the application is considered ready.Mesos doesn't gate traffic on /health so all pre-bind warmup needs to happen in
prebindWarmup()
