Fortio OTEL variant 1.76.0+dirty usage:
	fortio command [flags] target
where command is one of: load (load testing), server (starts ui, rest api,
 http-echo, redirect, proxies, tcp-echo, udp-echo and grpc ping servers),
 tcp-echo (only the tcp-echo server), udp-echo (only udp-echo server),
 report (report only UI server), redirect (only the redirect server),
 proxies (only the -M and -P configured proxies), grpcping (gRPC client),
 or curl (single URL debug), or nc (single tcp or udp:// connection),
 or script (interactive grol script mode or script file),
 or version (prints the full version and build details).
where target is a URL (http load tests) or host:port (grpc health test),
 or tcp://host:port (tcp load test), or udp://host:port (udp load test).
or 1 of the special arguments
