Add nanoswitch and cluster testing
Adds nanoswitch and the `switched-multi2` launch target to launch two Smalltown instances on a switched
network and enroll them into a single cluster. Nanoswitch contains a Linux bridge and a minimal DHCP server
and connects to the two Smalltown instances over virtual Ethernet cables. Also moves out the DHCP client into
a package since nanoswitch needs it.
Test Plan:
Manually tested using `bazel run //:launch -- switched-multi2` and observing that the second VM
(whose serial port is mapped to stdout) prints that it is enrolled. Also validated by `bazel run //core/cmd/dbg -- kubectl get node -o wide` returning two ready nodes.
