web: Reuse devices (#1165)

Implement feature for reusing an existing device (i.e., allow formatting
a block device or mounting a file system). Main changes:

* Redesign the dialog for changing location:
* Shows a table with all the devices that can be selected as location
for the volumes.
* Allows selecting how to allocate the file system at selected device
(create partition, create dedicated LVM, format, mount).
* Add a menu option in the table of volumes for resetting the location
(i.e., to use the installation device instead of a custom location).

Note: We have detected some problems with the UI for changing location
implemented in this PR:

* The table is scrollable. If there are too many devices, then there is
a chance of overlooking some devices if you don't realize about the
scroll.
* Having a table and group of radios at the end looks quite
overwhelming. The very same information could be provided in a simpler
way.
* Ideally, this change location option should be integrated in the form
of the volume.
