- Update defaults for v1beta2 and 3 to have URL scheme - Raname DefaultUrlScheme to DefaultContainerRuntimeURLScheme - Prepend a missing URL scheme to user sockets and warn them that this might not be supported in the future - Update socket validation to exclude IsAbs() testing (This is broken on Windows). Assume the path is not empty and has URL scheme at this point (validation happens after defaulting). - Use net.Dial to open Unix sockets - Update all related unit tests Signed-off-by: pacoxu <paco.xu@daocloud.io> Signed-off-by: Lubomir I.
