VOL-2098 Support for Kafka liveness testing
* Adds liveness channel to sarama_client and kafka_interadapter proxy.
The liveness channel will push true or false to the channel on
each successful or failed Kafka publish.
* Adds support to make a "liveness publish attempt", which publishes
an empty message on a _liveness channel.
* Adds ServiceStatusNotReady to Probe
* Suppresses multiple Probe.UpdateStatus of the same status
* Adds the ability to attach a Probe to the grpc server, so that
when the probe returns NotReady, the Server responds to requests
with UNAVAILABLE.
