Commit Message

[ADDED] Distributed Message Tracing (#5014)

When an incoming message contains the header `Nats-Trace-Dest` set to a
valid subject, the server will send there messages representing events
happening in each server where the message is processed.

The events will give details about ingress, subject mapping, stream
export and service imports, jetstream and egress to subscriptions and/or
routes, leafnodes and gateways. Except for a standalone server it is
expected to receive multiple trace messages for a given inbound message.

The header `Nats-Trace-Only`, if set to `true`, will produce the same
tracing events than without that header, except that the message will
not be delivered to subscriptions or inserted in the JetStream stream.
This is usefull to see the path that a message would take but without
affecting running applications.

Note that in a mixed environment where not all servers would be running
at 2.11+, when a message is supposed to be traced only and the remote
does not understand message tracing, the message will not be forwared
and the Egress event for that remote will indicate the reason.
