2 new CPU nodes added

[Predrag Punosevac]

Dear Autonians,

I just added two new CPU nodes 

lov1.int.autonlab.org
lov2.int.autonlab.org

to Auton Lab cluster. They each have two new Xeon Gold 6152 with 22
cores (44 threads per CPU) and 768 GB of RAM. You can already log and
use them. There are few rough edges that I need to fix tonight (I need
to add scratch directories and MATLAB) but other than that they should
be usable.

Cheers,
Predrag

P.S. We should be getting another CPU node with identical hardware specs
by the end of the week. I am also planning to repurpose Athena by the
end of next week for general CPU computing.
