There might be some new information that 3.7.8 CLI expects, but I'd
need to check to verify what it is. We don't really test the Gluster
CLI for backwards compatibility, as we expect the CLI to used with
GlusterD on it's own host. So when using the gluster CLI's
--remote-host option, with different versions of CLI and glusterd, the
user should expect some breakage sometime.

With REST support being planned for 3.8, I'd like to retire the
--remote-host option in its entirety. Going further, the user should
only use the REST apis, when attempting to do remote operations.
