Refactor volume manager

Registered by Dmitry Pyzhov on 2014-07-16

Our current implementation of volume manager is unsupportable. And we are going to use image based provisioning. It will have big impact on our volume manager.

There should be ability to add filesystem options for different roles: https://bugs.launchpad.net/fuel/+bug/1318614

There should be ability to not install boot partitions on empty partitions. And allow user to change list of boot partitions via cli.

Hell with storages: https://bugs.launchpad.net/fuel/+bug/1262313

Controller has unallocated space, by default, using ceph as image backend: https://bugs.launchpad.net/fuel/+bug/1295717

Another blueprint, maybe duplicate: https://blueprints.launchpad.net/fuel/+spec/improve-fuel-default-disk-partition-scheme
