This leverages recent additions to libkv enabling client
authentication via TLS so the discovery back-end can be locked
down with mutual TLS. Example usage:
docker daemon [other args] \
--cluster-advertise 192.168.122.168:2376 \
--cluster-store etcd://192.168.122.168:2379 \
--cluster-store-opt kv.cacertfile=/path/to/ca.pem \
--cluster-store-opt kv.certfile=/path/to/cert.pem \
--cluster-store-opt kv.keyfile=/path/to/key.pem
