As I wrote during/after the review on commit 2958c56e, “ganeti-cleaner:
Separate queue cleaning code”, while I appreciated the permission
separation, I didn't like too much the file-based approach:

- it is a very simple script, and lots of the code is duplicated
  between the two; I wouldn't like to see "ganeti-vmcapable-cleaner",
  "ganeti-master-candidate-cleaner", etc. in the future
- ganeti-master-cleaner "pollutes" the namespace, creating
  tab-completion conflicts with ganeti-masterd

This patch simply merges the master-cleaner back into cleaner, while
keeping the separate user permissions scheme, separate log files, etc.

Additionally, it fixes two bugs in the unit-test (not run with set -u
and wrong path in the master-cleaner log files test; yay for even
worse safety than Python?).

And finally, since we have now support for --help-completion, it adds
bash completion support for this script :) (needs to be applied on top
of my argument support patch series).

Now "gnt-instance recreate-disks" uses the default iallocator when "." is
specified as the iallocator. For uniformity, the same behavior applies to
these commands:
  gnt-node evacuate
  gnt-instance migrate
  gnt-instance add
"." is used instead of "default" becuse the latter could be a valid name for
an iallocator.

This patch adds code to wipe newly added disk space when growing disks
using “gnt-instance grow-disk”. “New disk space” is defined as the delta
between the old block device size (not necessarily equal to the amount
recorded in the configuration) and the new recorded size. Extra caution
is taken to avoid overwriting existing data. Unit tests are included.

A small typo in gnt-cluster(8) (“it's”) is also fixed.

This patch is somewhat longer than was anticipated. Before, commands like
“gnt-instance --help” would exit with the status code 1 (failure). With
this patch, those commands exits with 0 (success) while unknown commands
still print the usage screen and exit with status 1.

To achieve this goal without too much ugly code some refactoring on
cli._ParseArgs was necessary. Printing the version and usage screen was
separated. At the same time this allows for some unit testing.

The IAllocator class was handling all the requests on its own, passing

With the upcoming change to the IAllocator for MultiAllocate we can't

into separate classes, which just do their own stuff. It works similiar
to Opcode containers.

We will need to update the NEWS file later, but so far the RAPI

says it is "a number"), so it doesn't look like it needs update.
