Summary

Currently we output "Waiting for JSON parameters on stdin...", even if stdin is piped (for example, from echo).

Test Plan
> echo '{}' | arc call-conduit conduit.ping
{"error":null,"errorMessage":null,"response":"ip-10-161-81-110"}

> arc call-conduit conduit.ping
Waiting for JSON parameters on stdin...
{}
^D
{"error":null,"errorMessage":null,"response":"ip-10-161-81-110"}

I believe we don't require posix, and I don't want to require it. You can do this:

if (!function_exists('posix_isatty') || posix_isatty(STDIN)) {
  // print message
}
