Description
While investigating GENIUS-211 and using https://github.com/jhershberg/netvirt-ha-docker to run ODL clustered in a container, I've come accross this curious problem:
[laptop-host] $ ./karaf-client 1
[container] opendaylight-user@root> shell:stack-traces-print
[container] opendaylight-user@root>showSvcStatus --help
DESCRIPTION
diagstatus:showSvcStatus
show the status of registered services
SYNTAX
diagstatus:showSvcStatus [options]
OPTIONS
--help

What is fun is that if I do the exact same thing on a Karaf running locally outside of the container, with the exact same code (I'm using the binary which jhershberg/netvirt-ha-docker copied into the container), this this does not happen... so must have something to do with running in container and using dumb terminal (where "cursor arrow up" prints "^[[A" instead of working history).
May be it's somehow related to the @Option(name = "-n", aliases = {"--node"}) String nip; in DiagStatusCommand, because the exception above seem to happen just as it's about to print that option, here is the output from when it works (note how the -n, --node is missing above!):

So definitely very minor, and only filing this here for reference; not important enough to jump on fixing it; skitt FYI.
