Add test for version dispatching code

Based on the version of DRBD (as reported through /proc/drbd), the DRBD8
class chooses helper objects which adapt for the differences between
DRBD <= 8.3 and DRBD 8.4. This new test verifies that the proper objects
are created....

Add dependency on python-mock

Python Mock (http://www.voidspace.org.uk/python/mock/) is a mocking
library for Python. It is included in the standard Python distribution
as of Python 3.3, but has been around for quite a while. Debian unstable
contains a version we require....

Extract DRBD related tests

As the DRBD code was extracted from bdev.py, the corresponding tests
should as well be extracted into their own file. That's what this patch
performs.

Extract command generation logic from DRBD8

In order to easily support the DRBD 8.4 command syntax, this patch
extracts all command generation logic (i.e. where calls to `drbdsetup`
are assembled) into a new class DRBD83CmdGenerator.

Use DRBD84ShowInfo based on DRBD version

Now the DRBD8 class actually checks which version of DRBD is running on
the system and chooses the right class to parse the `drbdsetup show`
output.

Add `drbdsetup show` parser for DRBD 8.4

Common functionality between the DRBD 8.3 and DRBD 8.4 parser has been
extracted into BaseShowInfo. A test which verifies the behaviour is
included, but the DRBD84ShowInfo class is not yet used within the DRBD8
class....

Extract DRBD info parsing into drbd_info.py

Parsing the status (/proc/drbd) and `drbdsetup show` output takes quite
a bit of code, which has to be augmented by even more with the DRBD 8.4
support. So extract all the related classes into their own file.

Extract DRBD8ShowInfo class

This class parses the `drbdsetup show` output and represents it in an
easily accessible format. It got extracted so that 1) the DRBD8 class
can focus more on DRBD logic rather than parsing and 2) it's easier to
adapt the parser to new formats....

Add test for DRBD 8.4 /proc/drbd parsing

The current parser already supports the output of DRBD 8.4 /proc/drbd,
so add tests which actually verify this behaviour.
Note that the empty lines in proc_drbd84.txt are actually present in the
output of DRBD 8.4, they always appear when minors are not contiguous....

Add test for empty version in /proc/drbd

The previous patch removed a (rather implicit) test for /proc/drbd not
containing a version line. This adds an explicit test for this case.
