Issue MESOS-3310: Support provisioning images specified in volumes.
This is related to MESOS-3095 and MESOS-3227. The idea is that we should allow command executor to run under host filesystem and provision the filesystem for the user. The command line executor will then chroot into user's root filesystem. This solves the issue that the command executor is not launchable in the user specified root filesystem. The design doc is here: https://docs.google.com/document/d/16hyLVRL0nz-KBts1J5stGyxZPniFPbPbs7R-ZRQVCH4/edit?usp=sharing
