    Add Ubuntu 16 support (both x86 and aarch64). · a82f9ac8

    This is all pretty vanilla atop the Ubuntu 15 support.  Just new
    metadata files (passwd,group,shadow,gshadow); pulling in Kirk's Centos
    ntp.service; and an important tweak to the dhclient exit hook.
    
    resolvconf seems to be more prominently featured in Ubuntu 16, and it
    has a dhclient exit hook to alert the resolvconf stuff (so it can alert
    others) when nameservers change.  However, that hook somehow breaks DNS
    for our exit hook right as it calls sethostname.dhclient .  So to fix
    this, I just added a check for /sbin/resolvconf in the exit hook, and if
    that exists, we use the same elabinelab DNS-problem-avoidance strategy
    of manually invoking the tmcc binary with getbossinfo, so that the perl
    tmcc stuff doesn't hang in sethostname.client .  That works great.
    
    aarch64 (ubuntu16-ms) support is a very simple overlay atop the regular
    ubuntu16 dir; it only adds the special uboot boot.scr modification file
    we need.
