This mini-PR adds support to new tracing (
trace-dispatcher) for an environment variable that can provide a custom hostname to appear in trace / log messages:Setting the
TRACE_DISPATCHER_LOGGING_HOSTNAMEenvironment variable will override the system hostname in trace messages. This is equivalent to the legacy tracing system's envvarCARDANO_NODE_LOGGING_HOSTNAME.As
trace-dispatcheris and should be agnostic to its host application, the envvar's name had to change slightly.Furthermore, in the performance workbench, the PR sets those envvar to contain the node name, so that multiple nodes running on the same host can be distinguished from within a single trace message (convenience & consistency improvment).
