[Mesh] Tuesday exit node setup

Our current VPS provider for our exit node (VPN) is being even more annoying than usual. Asking us to prove that we aren't hosting specific content for which they've received DMCA complaints. We got two identical rack-mount servers donated via one of our members (who'm I'd like to give credit but they may prefer their privacy) and these should be perfect for exit node usage. My plan for Tuesday is to set them both up with nearly identical configurations and put one at Hurricane Electric later this week and another at sudo room, though the one at sudo room can remain powered off until the one at Hurricane Electric dies. Then we'd run a mesh-wide update to the node configuration, telling all nodes to switch to the new exit nodes. -- marc/juul
