Add `-q|--query [noderange]` for makegocons to list the console
status and the host server. If node is not registered in
goconserver, the status will be `unregistered`.
If console releated attribute is not defined for the specified
node but it is included in the noderange, error message for that
node will be printed at first.
Previously, it is impossible to know if the goconerver is started
by xcat. This patch add a marker in /etc/goconserver/server.conf
to help check the status. In addition, use server-cred.pem instead
of server-key.pem as it is not exist on SN.
This patch also control the service status of goconserver and conserver
when restarting the xcatd service on service node.
