Docker V1 protocol support has been officially deprecated by Quay and support will be
removed in the next major version. It is strongly suggested to have this
flag enabled and to restrict access to V1 push.

If enabled, Docker V1 push protocol will only be supported by those namespaces whitelisted
below. This feature should be left on unless general usage of the older
Docker V1 protocol is necessary.
