Added "vg" argument to the "gnt-instance ... --disk" syntax specification.
Now is ok to write:

gnt-instance add ... --disk N:size=NNg,vg=VG_NAME ...

But not all internal structures are ready to handle this yet.

Currently, the coverage reports include the unittests themselves, and
this skewes unfairly the reports, as the coverage for the tests is very
high (since they all run).

To fix this, we export the ganeti temp dir from run-in-temp-dir, and we
use that to exclude the tests directory. The patch also fixes a but
related to multiple directories to be omitted (--omit a --omit b is
wrong, it needs to be --omit a,b).

While starting to implement this, I found a number of deficiencies:

- Drop regular expressions. As it turned out, only very few fields for
  instances used them, all of which can easily be turned into static
  field names.
- Use two separate calls with a request and response description each.
- Add forgotten list of fields to query request.
- Add value status for case where a field is not available for an item,
  e.g. NIC 3 for an instance with only one network interface.
- Add "timestamp" field type.
- Updated examples.

Extend allocation functions to be aware of different vg names.  Suppose,
vg_name is helded in disk.physical_id[0] (already was) LUCreateInstance
is modified to be aware of new "vg" argument of the disk specification.

cfg.GetVGName() will only be used when no VG is specified.

The "add" and "remove" for plain and drbd instances should be correct.
The "move" for plain instance should be correct.

There are two issues: first, it's simpler to assign directly to pt
instead of via another local variable. Second, this code doesn't make
sense:
  if lt < 0:
    break
  pt = max(0, lt)

If lt is indeed < 0, then the code will break. Otherwise, lt ≥ 0, and
max(0, lt) will always be equal to lt. So we remove the extra
assignment.

Currently the test executes "/bin/sh -c 'trap "" TERM …" via the shell,
which means we have two shells involved (the parent one and the child
one, which does the trap). For some weird reason, this works for older
OSes: the first shell exec's the second one, whereas on squeeze it forks
and only then exec. This might be due to changes in Python or bash or
whatever.

In any case, the point is that this is a hacky way to call a shell, so
we change this to simply execute the desired shell directly, without any
intermediate shells (I don't understand why it was written as such
originally).

Currently, reinstallation of a DRBD instance with the secondary node offline does:

node1# gnt-instance reinstall -f instance1
Waiting for job 139053 for instance1...
Thu Nov 18 01:36:09 2010  - WARNING: Could not prepare block device disk/0 on node node3 (is_primary=False, pass=1): Node is marked offline
Thu Nov 18 01:36:09 2010  - WARNING: Could not shutdown block device disk/0 on node node3: Node is marked offline
Job 139053 for instance1 has failed: Failure: command execution error:
Disk consistency error

Since this fails anyway, let's check the secondary nodes, thus
preventing any modifications to the instance (e.g. OS type change):

node1# gnt-instance reinstall -f instance1
Waiting for job 139058 for instance1...
Job 139058 for instance1 has failed: Failure: prerequisites not met for this operation:
error type: wrong_state, error details:
Instance secondary node offline, cannot reinstall: node3

The patch needs modifications to the _CheckNodeOnline function, in order
to display meaningful messages ("Can't use offline node" would be very
confusing for an instance reinstall, since we didn't select a node
manually).

This patch changes the Makefile rules to build the man pages from the

Note: pandoc quotes by default the ‘@’ character in manpage output, so
we explicitely undo this before writing the .in file.

Note 2: The docs unittest has switched from checking cmdsynopsis
elements to search for either '**command**' or '| **command**' at the
beggining of lines. This is not as safe as the sgml checker, but it
should be fine.
