If present in the kamaki configuration file, the user will read
the ~okeanos credentials using the kamaki config interface.
Whenever the user changes the ~okeanos credentians, the changes are
pushed back to kamaki.

Not fully implemented yet

Fixed many `E127 continuation line over-indented for visual indent'
errors

Before extracting an image or registring it with cyclades, the image
properties are populated with metadata concerning excluded deployment
tasks.

Most partition manipulation programs leave 2048 sector empty space
after the last partition.

The method used a wrong warning output function

vfs_uuid is more suitable for this and it whas added before blkid
in guestfs, hence it is supported in more guestfs versions.

Inform the user about metadata changes performed during syspreps
execution or image shrinking.

Also fix various issues. snf-image-creator-dialog is almost ready.
Some `Help' entries are missing.

Also create a new output class (InfoBoxOutput) to be used when
performing syspreps

This method returns a sysprep object with a given name. Now,
(enable,disable)_sysprep work with sysprep objects instead of sysprep
names

The do_sysprep method was not updated to comply with the changes
made in list_syspreps method

Populate Sysprep entry in "Image Customization Menu". Not fully
working.

This method takes a sysprep object as argument and returns the name
and a description for this object.

The method used to return 2 lists of enabled and disabled sysprep
object. Since sysprep objs contail an `enabled' attribute, it is easy
to determine which of those are enabled and which are not. There is
no need to return 2 seperate lists.

This dir will host help files used by snf-image-create-dialog

Image properties manipulation works fine.

Extract and Register menu entries work fine.

Otherwise the registration may fail.

If no customization is to be applied the image should be mounted
readonly.

Let the application decide what to do with them. If image-creator
receives an error from kamaki it will terminate. But this may not be
the proper thing to do for an interactive application like
image-creator-dialog

snf-image-creator-dialog is a dialog based version of snf-image-creator
Nothing works yet

Add an option to DiskDevice's mount method to allow readonly mount

The error function main.py used for outputing errors has been removed
and the code was not updated to use the error method of SimpleOutput
output class.
Also did a minor cleanup: git_os_class function was renamed to os_cls

In older versions of libguestfs, the recovery process did not close
the file descriptors it inherited. This could case problems if the
parent process had open pipes.

This is handy because now progress class can print using the output
methods of it's output class
