	This vendor change was purely for the changes in docker to allow for setting the Masked and Read-only paths. See: moby/moby#36644 But because of the docker dep update it also needed cadvisor to be updated and winterm due to changes in pkg/tlsconfig in docker See: google/cadvisor#1967 Signed-off-by: Jess Frazelle <acidburn@microsoft.com>
