Gogs/Git scheduled maintenance

[Predrag Punosevac]

Dear Autonians,

I would like to take Gogs down today at 2:30PM for about 1h to do some
upgrades. Once the server is up you might need to clear .ssh/known_hosts
from old Gogs ssh fingerprints. On the related note if you are using 
upload.autonlab.org you will need to do the same. Migration is already
done. This is related to the recent hardware failure of few servers with
faulty Atom chipsets.

Best,
Predrag
