2017-05-09: Abisko ordinary login node now online, running Xenial

The ordinary login node of Abisko is now online again running Xenial with a similar setup as the one used on Kebnekaise.

There is one other user visible change and that is that the Abisko login node has gotten a new ssh host key.

Most of the ssh clients will complain about this if they have saved the old key.

A message looking something like the following will be seen (this is from a linux ssh session and might be different if using putty or wome other tool):

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
SHA256:45IHbzcszpuoRIHay0m7L2gEsATIUsR3wKOddNptUTU.

This is expected until you have deleted the old ssh key for abisko and accepted the new one.
