Description

If the Mesos master supports hierarchical roles but the agent does not, we need to ensure that we avoid putting the agent into a bad state, e.g., if the user creates a persistent volume.

One approach is to use an agent capability for hierarchical roles, and disallow creating persistent-volumes using a hierarchical role if the agent doesn't have the capability. We could also use an agent version check, although until MESOS-6975 is implemented, that will be a bit awkward.
