Eventing

Created a new in-memory Channel which buffers events and decouples
sender and receiver. The previous in-memory-channel implementation
was blocking and senders would block until the event had been
delivered to the destination. (Thanks to @sbezverk)
Add NATS ClusterChannelProvisioner. (Thanks to @radufa)
Separated several ClusterChannelProvisioners from the core. (Thanks to @matzew)
Add a Knative-message-history attribute recording the channels
traversed by the event
(#688)
Several eventing resources (ClusterChannelProvisioner, Subscription,
in-memory, GCP PubSub channels) now emit corev1.Events to improve
debugging (#746).
Cleanup of Conditions to hide Severity=Error when conditions are
ready.
Improved cleanup of subscription and reply.
Fixes to ensure Istio injection in the knative-eventing namespace.
