New storage settings for different target devices

[joseivanlopez]

Problem

There are three main different scenarios to be supported by the storage proposal:

• a) Install in a target disk device (e.g., disk, RAID, DASD, etc).
• b) Install in a new LVM volume group.
• c) Reuse an existing LVM volume group.

Moreover, the proposal should be able to indicate the following boot options:

• a) Whether to configure or not separate partitions for booting.
• b) What device to use for creating the booting partitions.

Solution

Adapt the storage settings to support all the scenarios described above:

Target                 s (options: "disk", "newLvmVg", "reusedLvmVg")
TargeDevice            s (optional: does not make sense if Target is "newLvmVg")
TargetPVDevices        as (optional: only makes sense if Target is "newLvmVg")
ConfigureBoot          b
BootDevice             s

Testing

• Added and adapted unit tests
• Tested manually

NP: although the FIXME comment has been drop, I still thinking we should pass the targetDevice, not only its name, to the "BootdeviceSelectorDialog" or whatever component we're going to create.

Ok, let's do it as part of the other PR, #1106.

It's hard to be sure with such a big PR, but in general LGTM.
