This patch adds a new log handler class based on the standard library's
BaseRotatingHandler. This new class allows the log file to be re-opened,
e.g. upon receiving a SIGHUP signal. The latter will be implemented in
forthcoming patches. The patch does not change the behaviour regarding
writing to /dev/console.

Quite a bit of code had to be changed to unittest the log handlers.

This patch implements recreation of instance disk symlinks when the
activate-disks operation is run. Until now, it was not possible to
re-create these symlinks without stopping and starting or migrating an
instance as the RPC call where this is done was in instance startup
and migration.

In order to do this, the blockdev_assemble rpc call needs the disk
index too, which is added to the protocol. This is a change from 2.3
and makes instance startup incompatible (FYI).

Currently, the validity of the hypervisor parameters is only checked
at init/modification time, and not in the cluster verify. This is bad,
as it can lead to inconsistent state that is only detected when the
next modification (which can be unrelated) is made, leading to
unexpected error messages.

This patch adds both syntax verification (in masterd) and validity
verification on remote nodes. The downside of the patch is that on
clusters with many instances which have custom parameters, it will be
slow. A possible improvement would be to detect duplicate, identical
set of parameters, and collapse these into a single verification, but
that is left as a TODO (in case it becomes problematic).

An additional change is in utils.ForceDict, where we said 'key',
whereas this function is always used with parameter dicts, so I
changed it to "Unknown parameter".

The recent work on multi-VG support has converted LUClusterVerifyDisks
into doing serialised calls to each node, as each node can have
different VGs. This is suboptimal, especially for big clusters, where
this LU is executed by the watcher very often.

This patch changes the logic based on the observation that querying a
node for its VGs and then requesting a LV list for those VGs is
equivalent to simply asking for all LVs, without specifying the VG
name(s). So backend.py needs changes to accept an empty VG list, and
the LU itself partially reverts to the previous version.

Additionally, we do two other fixes to this LU:

- small improvement in getting the instance list from the config
- MapLVsByNode works for all disk types, hence no need to restrict to
  the DRBD template, especially as today we can "recreate" disks for
  plain volumes too (the warning message in gnt-cluster is updated
  too)

Recent multi-VG work already exports the missing LV names as vg/lv,
not simply lv. So the query and addition of the VG name in gnt-cluster
verify-disks is redundant, and even wrong for non-default-VG
instances.
