This design describes a tool that will perform automatic repairs on
instances when they are detected to be unhealthy (living on offline or
drained nodes, at the moment). These repairs can be scheduled
automatically or requested as a one-off by a tool or person.

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.

Debian Wheezy will ship with this version, and it has many improved checks compared to 0.6, so let's:

- bump version in the docs
- silence some new checks that are wrong due to our indent=2 instead of 4
- fix lots of errors in the code where the indentation was wrong by 1
  or 2 spaces
- fix a few cases of == True, False, None and replace with 'is'
- re-indent some cases where the code is OK, but pep8 complains

To change the cluster from single homed to multi homed or vice versa one
must target the master node first, and pass the --force option. All
other nodes then will work as long as they are reachable by the master.

Note that this will also prevent a node to be set to single-homed if the
master is multi-homed, which wasn't disallowed before, and warn if a
single-homed <-> multi-homed transition happens.

Also note that it's still theoretically possible to flip a cluster
inadvertently by changing the master node this way, and then doing a
master failover before fixing the other nodes.

While reviewing the RAPI docs (for commit 003306f9), I realised that
the punctuation used in RAPI is inconsistent, especially with regards
to definition lists.

This patch changes all such lists to not have punctuation, except for
one case (the ecode descriptions, which have multiple
paragraphs). Furthermore, it fixes the few opcodes which had docs
ending with punctuation to not do so anymore.
