This is needed in a new test script for cfgupgrade where it's better
to only use the minimum parts necessary for testing cfgupgrade.
Including full configuration data to ensure verification doesn't fail
would make maintenance difficult.

In the condition for checking the configuration directory, one “or” should have
been an “and”. This bug was in cfgupgrade since commit 95e4a814 (June 2008).
Found thanks to a test script.

Since configuration changes are now usually done in the configuration
writer class, cfgupgrade's only task is to change the config version.
This means we can easily support upgrading from Ganeti 2.0 and 2.1 to
2.2.

This patch also brings a couple of small cleanups.

Since utils.WriteFile requires an absolute path, cfgupgrade needs to

Commit 43575108 added bootstrap.GenerateclusterCrypto and commit
7506a7f1 changed cfgupgrade to use it. However, this lost the
functionality of upgrading in non-default DATA_DIR.

To fix this, we enhance bootstrap.GenerateclusterCrypto to accept custom
file paths for the three files it modifies. If more files will be needed
in the future, we could just pass in modified DATA_DIR, but for now it
suffices.

Information exchanged between different clusters via untrusted
third parties (e.g. for remote instance import/export) must be
signed with a secret shared between all involved clusters to
ensure the third party doesn't modify the information.

Currently, the ganeti-confd's HMAC key is called “cluster HMAC key” or
simply “HMAC key” everywhere. With the implementation of inter-cluster
instance moves, another HMAC key will be introduced for signing critical
data. They can not be the same, so this patch clarifies the purpose of the
“cluster HMAC key” by renaming it. The actual file name is not changed.

The logging functions expand the arguments themselves, thus it's safer

This patch makes cfgupgrade work on empty cluster (i.e. no instances),
up to a point that the config file can be converted from 1.2 to 2.0.
This is not yet complete, though.

This changes the raising of exceptions from:
  raise Exception, value
to
  raise Exception(value)

as the first form will be removed in python-3000 and the second form is
preferred now.

The changes also involve a few cases of changing from raising standard
exceptions and use our own ones.

The new version also fixes many pylint-generated warnings, especially in
ganeti-noded where I changed many methods to @staticmethod.

There is no functionality changed (barring any bugs).
