[system-tests] Need to implement checks for unallocated disk partitions

[Anastasiia Naboikina]

It`s necessary to check node disk partitions for unallocated space. It`s exceptionally important due to bug: https://bugs.launchpad.net/fuel/+bug/1295717

We need to make the following checks:
- check that in simple mode using Ceph for Glance by default all storage on Controller is partitioned as Base System space;
- check that in simple mode not using Ceph for Glance there are partitions for Base System storage and for Image storage, but there is no unallocated space;
- check that when combined with Ceph role, Controller has no unallocated space (space
is partitioned between Base System storage and Ceph storage).

2 and 3 case still will have unallocated space on first available disk, fixing this will require proper refactoring of allocation logic in nailgun, or hacking it in a bad way

    Add check for unallocated space on controller

    Added check for presence of unallocated disk space
    on controller node in case Ceph for image storage
    is used. All disks on controller should be
    allocated for Base System space.
