Adding a warning when /boot is reasonably too small (#738)

* Moved convert_size_to_gb() into disk/helpers.py, Added a Partition().size property meta function. Using the .size value to check if /boot is too small which will raise an exception. The only drawback is that it's done post-formatting. This in order to catch scenarios where formatting isn't used.
* Changed /boot warning from 0.15GB to 0.25GB
* Changed the wording in the warning when /boot is too small.
