More design details will be added regarding setting up the node daemon,

This was requested in issue 301. Before this patch, requests to
“/2/query/*” and “/2/instances/*/console” would require authentication
with a user with write access. Since that is not strictly necessary, a
new user option named “read” is added.

Console information can also be retrieved as a normal query, therefore
the change applies there too.

This was the first user option to be added after “write”, therefore
quite a few changes were necessary. Documentation, including NEWS, is
updated as well.

Other places, such as “ssh.GetUserFiles”, use a structure where the

did the opposite, that is the public key came first. To avoid confusion

While writing the initial version of this design I misunderstood what
“setup-ssh” does. It doesn't actually start the node daemon and just
configures SSH, nothing else.

This patch adds the cluster name as a field to the JSON structure and

This patch cleans up  the Haskell library detection and defaults.

First, it makes the base compiler/libraries required, per the email discussion.

It then adds two new small autoconf macros, on to check for a required
Haskell library and one to do custom action based on test results. We
use these macros to cleanup and simplify a bit the module detection:

- rapi, confd, and split query are auto detected and enabled if _all_
  required libraries are present
- unittests are enabled if _all_ required libraries are present

The patch also updates the documentation regarding required libraries.

After this patch, base Ganeti fully buildable on Debian Squeeze/Ubuntu
Lucid.

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).

This patch replaces our home-grown, and quite limited, test runner
infrastructure with test-framework
(http://batterseapower.github.com/test-framework/

). The rationale for
doing so is as follows:

- we will need to add support for HUnit tests, so either we add more
  custom code or we switch to an existing library
- test-framework is mature and already packaged, at least in
  Debian/Ubuntu
- it supports more features: parallel test running, better test
  selection, etc.

As you can see, the changes are trivial, and don't touch the tests at
all; if/when we split the QC.hs file into per-module files, then we
could drop QCHelper too, and replace it with test-framework-th, which
does the same, but even more automated (auto-discovery, without having
to list the tests at all).

Dependencies are updated in devnotes.rst; note that I've already added
the hunit dependencies since we're going to use that soon.
