    That all seems reasonable to me.  I can't find any examples of environment variables being
accessed from in the Java code.  I assume we don't want the name of the environment variable
hard-coded in the hostname resolution code, but I'm not sure of the best place to define it,
    Thoughts?  I could put it in `ExecConstants` but it would be the only env variable in
there.  I could also just make it a static variable in the `ServiceEngine` class.
    Do we still want to provide the option to override through a system property, or just
rely on the environment variable?
