This patch introduces a test to check the compatibility

This patch introduces and enhances generators for
instances:
- 'genInstWithNets' is split into the generation of an
  arbitrary instance and enhancing an instance with nets
- 'genInst' calls 'genInstWithNets' with an empty set
  of initial networks to provide a reasonable default
- the Arbitrary instance of 'Instance' uses now 'genDisks'
  to create instances with a reasonable set of disks

The Arbitrary instance of the 'Instance' object is written
using the <*> syntax. Since it often uses the 'arbitrary'
generator for the instance's fields it is hard to figure
out which 'arbitrary' fills which instance field. This
patch annotates all fields with their name to make
maintenance of this code easier.

This patch adds generators for Disk instances to the Haskell
test code. It uses somewhat more reasonable generators to
fill the fields instead of just arbitrary values.
'genDiskWithChildren' is a generator that generates a disk
with a specified number of disk children. To avoid shooting
ourselves in the foot we do not generate further (grand)
child disks for the child disks. 'genDisk' calls
'genDiskWithChildren' by requesting three children as a
resonable default.

The monitoring daemon should always be alive, therefore it's added to the

Add the monitoring daemon to the command starting the node daemon, given that
they both have to be started on all nodes.

Note that daemon-util only supports starting one daemon at the time, so the
actual command has to be composed as a sequence of two different daemon-util
invocations.

Also, the monitoring daemon invocation is conditional, depending on whether it
was enabled at configure time.
