Damien ef4211afe5 Rename devices to <area>-<role> scheme 
DC fabric: spine/leaf/border-leaf/access/host -> dc-spine, dc-leaf,
dc-border-leaf, dc-access, dc-server. Campus border leafs flipped
from border-leaf-campus to campus-border-leaf for consistency. Core,
campus spines/leafs/access/hosts unchanged.

Updates topology, annotations, all configs (hostnames + peer
descriptions), host interface files, README, TROUBLESHOOTING,
END_TO_END_TESTING, and the SVG diagram.
