This commits enables the DRBD data collector to use the Confd client to
gather information about the pairing between DRBD minors and instances.

For testing purposes, the DRBD data collector now requires either zero
or two parameters: one is the DRBD file, one is the pairings file.
When no parameter is passed, the collector is in "production mode" and takes
the data from /proc/drbd and from the Confd client.

The shell tests of mon-collector are updated accordingly.

Found while doing the previous .dot file changes and wondering what's
this "doc/*.in" stuff… it looks like these were obsoleted over the
years by not paying attention on cleanup patches:

- doc/build: obsoleted by commit 13de7d59
- doc/*.in: obsoleted by commit 2ab2b9f5
- doc/html: was always a directory since its introduction in commit
  d17e74b4, mark it as so
- devel/clean-cluster: was introduced with initial .gitignore addition
  (commit 7a47c582), but we don't actually generate it

This removes entirely the standalone dot files by inlining them in the

The first dot files we added way back in the 2.0 release are managed
manually: we build the .pngs ourselves, track them in .gitingore,
etc. Since then, we have switched to allow sphinx to build/manage them
itself, so it makes sense to cleanup the build system and covert
everything to this simpler method.

This patch simply converts from "image: x.png" to "graphviz: x.dot",
as an externally-referenced dot file, and removes all the custom
makefile rules for png conversion. The next patch will bring the
conversion further (by inlining then).

Additionally, while checking that the patch doesn't change the html
output, I saw that the use of "shape=diamond" with non-trivial labels
results in very ugly diagrams; so we split the question in such
decision boxes to make them more reasonably looking.

I don't remember why I introduced these when switching to pandoc, but
they are not absolutely needed. Instead of pre-generating them (which
might save some trivial cpu time), we can simply pass footer.rst as an
additional input file to pandoc.

The advantage in doing so is that semantic information is preserved;
when pre-generating and including them as-is, the entire structure is
lost, as pandoc won't reinterpret them, so things like a potential
table of contents will simply ignore the footer.

The patch also adds a new target to rebuild all man pages (both groff
and html formats), for testing changes to the pages easier.

While trying to understand why some code was not being tested, I
realised that we have a bad data type in Hcheck.hs.

We have "data Level = GroupLvl | ClusterLvl", but then we need to pass
the group name/index as well, so we have functions that look like the
following:

  f :: Level -> Maybe String -> …
  f GroupLvl (Just gname) = …
  f GroupLvl Nothing = … -- never used
  f ClusterLvl _ = … -- wrong, since a (Just x) could be passed

It's clear that we just need to move the group name in the "GroupLvl"
constructor, and simplify the call chain.
