fixed juniperconnect::disconnectssh for netconf, test::analyze_* returns output, enhancing juniperconnect::build_rpc
added juniperconnect::add_to_rpc and testing for it
juniperconnect: changed build_rpc to default to indent 0 due to line length limits, send_rpc will now output a formatted rpc to the screen unless quiet rather than the unformatted one
bugfix for juniperconnect::disconnectssh
