Commit 96276ae7 added the above opcode, but forgot to update the OP_ID
per our previous mailing list discussions. This patch makes the OP_ID
be consistent with the other IDs (OP_$object_$action).

Commit f5677ab3 added the _VerifyOob functionality, but there are two
issues with this function:

- a real bug, as objects.Node doesn't have a 'master' attribute
- a design bug, as we need to verify the OOB programs not only on
  current masters, but on all nodes that can become masters via the
  auto-promote functionality; otherwise, an automated cluster operation
  could cause the cluster to become inconsistent (error in verify)

The Node.master bug didn't appear in QA because it is triggered only
with non-master-candidate nodes, and our QA doesn't test this
combination (and neither other node flags combination).

As it's quite easy to forget updating the protocol version (and was
actually forgotten for Ganeti 2.3), it is now derived from the
configuration version (which is equivalent with the Ganeti version). The
protocol version for Ganeti 2.4 will be 2040000.

Patch 03941a26 made disk growth VG-aware, but the code has a bug: it
only works for LD_LV disks, and not LD_DRBD. To fix it, we add a
generic function to compute the per-VG growth requirements, and switch
to using that instead of manual build.

Furthermore, since the function _CheckNodesFreeDiskPerVG always takes
its input from this new function or _ComputeDiskSizePerVG, we change
the latter to always return a dict (possibly empty), instead of either
a dict or None. This makes the types more consistent.

Since the --master-netdev option is now used both at cluster init and at
cluster modify time, it cannot have a default value of DEFAULT_BRIDGE
(xen-br0) anymore. As such at cluster init we make the initialization
explicit if another value hasn't been passed. This fixes gnt-cluster
modify changing the master_netdev to xen-br0 if called without that
argument.

Passing tap devices to KVM as file descriptors requires that the respective
file decriptors remain open during utils.RunCmd execution. To this direction,
we add a “noclose_fds” keyword argument to utils.RunCmd, accepting a list of
file descriptors to keep open. The actual fd handling is implemented in
_RunCmdPipe and _RunCmdFile using subprocess.Popen's “preexec_fn”[1],
since subprocess.Popen provides no other way to selectively handle fds.

A small modification is also made to test/ganeti.utils_unittest.py to comply
with _RunCmdPipe's new API and a new unit test is added to test the selective
fd retention functionality.

     the child process just before the child is executed. (Unix only)”
