This commit is the minimal set of functionality needed to allow users to create a configuration policy that gcs can enforce. Policy enforcement will allow users to state "only these containers, with these command lines, etc etc" should be run. If anything in gcs doesn't match the user supplied policy, it will end container run and report an error. Currently, only container filesystem policy is enforced. This is done at two points. When a pmem device is mounted, its dm-verity root hash is checked against policy to see if it is allowed. At the time of overlay creation, the order of layers is compared to policy to make sure that the container is being constructed as the user expected. Additional policy enforcement that is coming in future commits includes: - enforce policy for scsi mounts - enforce container command line - enforce environment variables

This commit is the minimal set of functionality needed to allow users
to create a configuration policy that gcs can enforce.
Policy enforcement will allow users to state "only these containers, with these
command lines, etc etc" should be run. If anything in gcs doesn't match the
user supplied policy, it will end container run and report an error.
Currently, only container filesystem policy is enforced. This is done at
two points. When a pmem device is mounted, its dm-verity root hash is checked
against policy to see if it is allowed.
At the time of overlay creation, the order of layers is compared to policy to
make sure that the container is being constructed as the user expected.
