Collect number of disks and disk size

[Jean-Baptiste Lallement]

[Impact]
 * Currently the guided methods of the Ubuntu installer only address single disk setup. When a user have several disks on his machine he has to use the manual partitioning which is prone to failure for inexperienced users.
 * It would be useful to understand how many disks are installed on a system and their size to determine how update the installer to best suit users' needs.
 * We only report mounted partitions size

[Test Case]
 * Install the new version from -proposed
 * run `ubuntu-report show`
   -> check that there is a Disks field, corresponding to arrays in GiB of disk sizes attached to the system. Non spinning disks, ssds or virtual machine disks are ignored.

[Regression Potential]
 * As with the rest of ubuntu-report code, any error results in an empty, and so ommitted field. We report as many valid values as possible and discare invalid ones.
 * Backed up via a lot of new and existing tests, checking corner cases like no valid size/number of block, empty size/number of block file, missing partial informations from the kernel, ignoring loop and other random devices…

Currently the guided methods of the Ubuntu installer only address single disk setup. When a user have several disks on his machine he has to use the manual partitioning which is prone to failure for inexperienced users.

It would be useful to understand how many disks are installed on a system and their size to determine how update the installer to best suit users' needs.

This information is available from /sys/block/<device>/size . The information is in blocks. The block size is available from /sys/block/<device>/queue/{logical|physical}_block_size

For example on my system

$ cat /sys/block/sda/{size,queue/*_block_size}
125045424
512
