cloud-noc-os01: add group and access to sysadmin-copr
    
    This noc host in rdu-cc is used for pxe installs, dhcp server and also
    to access the private mgmt network for hosts in rdu-cc. Setup it's own
    group and add sysadmin-copr to access it so they can get to the mgmt
    interfaces on various copr machines there to reboot them.
