The ProxyGroup CRD specifies a set of N pods which will each be a tailnet device, and will have M different ingress or egress services mapped onto them. It is the mechanism for specifying how highly available proxies need to be. This commit only adds the definition, no controller loop, and so it is not currently functional. This commit also splits out TailnetDevice and RecorderTailnetDevice into separate structs because the URL field is specific to recorders, but we want a more generic struct for use in the ProxyGroup status field.
