Description
Verify that the Docker server certificate file (the file that is passed along with --TLScert parameter) is owned and group-owned by root.

Hence, it must be owned and group-owned by root to maintain the integrity of the certificate. By default, the ownership and group-ownership for Docker server certificate file is correctly set to root.
