If refoutput is true, then the output will be returned as a
If refoutput is 1, then the output will be returned as a

If refoutput is 2, then the response structure will be returned
as output. runxcmd will not parse the request structure.
Do not use the scalar string input for xdsh unless you are running
a simple single-word command. When building your request hash,
the entire command string xdsh runs needs to be a single entry
