* Fix streaming RPCs for agentless.
This PR fixes an issue where cross-dc RPCs were unable to utilize
the streaming backend due to having the node name set. The result
of this was the agent-cache being utilized, which would cause high
cpu utilization and memory consumption due to the fact that it
keeps queries alive for 72 hours before purging inactive entries.
This resource consumption is compounded by the fact that each pod
in consul-k8s gets a unique token. Since the agent-cache uses the
token as a component of the key, the same query is duplicated for
each pod that is deployed.
* Add changelog.
