[PATCH] master. The new create.

[Joel Granados Moreno <jgranado redhat com>]

Hello list

Been working on a Custom Partitioning workflow.  Based on 
https://fedoraproject.org/wiki/Design/AnacondaStorageUI/MiscMockupIdeas

In this patchset there are two big changes:

1. In the LV edit the user no longer has to go through the intermediary
step of the Volume Group.

2. There are only 4 buttons in the main customization window.  The new
"Create" button replaces the LVM, RAID and New buttons.  It will
automatically search for the valid options (So the user wont try to
create an lvm when there are no PV present.)

For 2. There are also some new information strings.  The RAID info is
taken from the old messages so no translation would be needed.  There is
an LVM message.  Its long and I would like to see it a little shorter
(anyone want to give it a try).

Caveats:
1. LVM Logical Volume does not work yet.  We need to relate it to a VG
someway,  not sure how to do that yet.  The LV can still be created
through the VG interface.

2. Definitely thinking of changing hasFreeHardDrive for something in
storage.__init__.

3. This adds some click to some parts of the install but we add
consistency and context info.  We also check stuff before errors happen,
so we don't need some error messages (Like trying to create partition
when there is no free space)

Review appreciated.

regards.
