We replace the bootstrap service with a headless service and have all nodes connect directly to the pod ips. This exposes a bug where nodes are stuck with zero connections if they try to connect too early. This was previously masked by kubeproxy. We fix that by adding an init container which waits for the first bootstrap node to accept connections. The bootstrap attribute is now declarative: we no longer consider every baking node as bootstrap. The bootstrap: true must be passed in values.yaml We add headless services in order to give the pods a meaningful FQDN. Rename "bootstrap" statefulset to "baker" to reflect this new model. Other changes: * do not hardcode the protocol version in the key-importer script, pass it as a variable instead * In values.yaml, baker nodes and regular nodes are now listed separately, which simplifies the code in other places. * invited values always has one node even though the main topology may have several. To add more nodes to an invite, edit the yaml manually. fix oxheadalpha#69

invited values always has one node even though the main topology
may have several. To add more nodes to an invite, edit the yaml
manually. fix Invite yaml should only contain a single peer node oxheadalpha/tezos-k8s#69
