Removes tcpOnly and ephemeralKeys: reifying them as nixos options adds little beyond improved discoverability. Until 17.09 we'll automatically translate these options into extraArgs for convenience. Unless reifying an option is necessary for conditional computation or greatly simplifies configuration/reduces risk of misconfiguration, it should go into extraArgs instead.
