Switch ovh/GRA1 to opendev.org mirror
This is our second kafs based mirror (rax.IAD being the first), chosen
to be geographically remote to the AFS servers.  It is currently
manually configured with 5.2-rc7 kernel, which has all the current
kAFS fixes incorporated.
Switch it in for initial testing
# new opendev.org based mirrors, but then eventually be removed once
# all are updated.
