             Summary: Pull provisioner from linux filesystem isolator to Mesos containerizer.
                 Key: MESOS-4240
                 URL: https://issues.apache.org/jira/browse/MESOS-4240
             Project: Mesos
          Issue Type: Bug
            Reporter: Jie Yu


The rationale behind this change is that many of the image specifications (e.g., Docker/Appc) are not just for filesystems. They also specify runtime configurations (e.g., environment variables, volumes, etc) for the container.

Provisioner should return those runtime configurations to the Mesos containerizer and Mesos containerizer will delegate the isolation of those runtime configurations to the relevant isolator.

Provisioner will return a ProvisionInfo (a protobuf) which will be passed to isolators (the 'prepare' interface). ProvisionInfo includes an optional 'rootfs' and image specific runtime configurations (could be the Docker/Appc manifest).
