A new function for formatting the query results is added,
``FormatTable``. This was determined to be easier and safer than
modifying the existing ``GenerateTable`` function while keeping
backwards compatibility for code not yet converted. The new code makes
use of the enhanced information provided by query2.

Changing the volume group is a lot less frequent than acting on a node
group. As such we drop the "-g" shortcut and require the long option to
be passed. In 2.3 the commands which used to accept the volume group as
"-g" won't have any node group option, so no confusion will arise. Later
on we may pass "-g" as the initial node group name to gnt-cluster init,
although that's not strictly necessary, as modifying it later is always
possible.

This patch adds an initial implementation of a lock monitor, accessible
for the user through “gnt-debug locks”. It currently shows all resource
locks: BGL, nodes and instances. Config and job queue locks could be
shown too, but wouldn't be of much help.  The current owner(s) and mode
are also shown.

Showing pending acquires will require further changes on the SharedLock
internals and is not yet implemented.

Example output:
$ gnt-debug locks -o name,mode,owner
Name            Mode      Owner
BGL/BGL         shared    JobQueue19/Job147

Currently cli.py unconditionally adds the dry-run option. This patch
disables this, and exports dry-run as a normal option.

The other alternative I tried to implement (adding a new fake option for
disabling the auto-add per individual command) would require changes in
more places, as the list of options is no longer a homogeneous list.

This patch enables IPv6 name resolution by using socket.getaddrinfo
instead of socket.gethostbyname_ex.

It renames the HostInfo class to Hostname and unifies its use throughout
the code. This is achieved by using static calls where no object is
needed and removes some obsolete code.

For now, we just resolve to IPv4 addresses, but this will change once it
is needed.

Currently, if the cli.JobExecutor class is being used, and one of the
jobs is being archived before it can check its result, it will raise a
stracktrace as _ChooseJob is not prepared to handle this case.

This case makes JobExecutor work better with lost jobs (it still reports
them as 'failed', but it doesn't break and returns a proper error
message), and modifies the generic FormatError to report the JobLost
exception properly, instead of as "Unhandled Ganeti Exception".

Since JobExecutor is hard to test properly, I only tested this manually,
via a fake invocation.

This is needed because not just the cli scripts need this decorator, but
the master daemon too (and it already duplicated the code once).

In cli.py we just leave a stub, so that we don't have to modify all the
scripts to import rpc.py.

We then change the master daemon code to reuse this decorator, instead
of duplicating it.

This patch adds a new vcs-version file that is generated via git (and
can be adapted if VCS is changed) and then embebbded as VCS_VERSION in
the constants module.

This means two things:
- local modifications without committing to git (or when using a tar.gz
  archive + mods) will not be reflected
- version is fixed at the time of the last make regen-vcs-version (dist time,
  or devel/upload which calls this)

Thus this is more geared at developers rather than end users.

The patch:

- adds rules for generating the vcs-version file
- adds a dist-hook for re-generating the file (if possible) and copying
  the updated version to the distdir
- modifies devel/upload to re-generate the file before upload

The output of --version will look like:
gnt-cluster (ganeti v2.2.0beta0-184-gebca7e6) 2.2.0~beta0

Since migration live/non-live is more stable (e.g.) for Xen-PVM versus
Xen-HVM, we introduce a new parameter for what mode we should use by
default (if not overridden by the user, in the opcode).

The meaning of the opcode 'live' field changes from boolean to either
None (use the hypervisor default), or one of the allowed migration
string constants. The live parameter of the TLMigrateInstance is still a
boolean, computed from the opcode field (which is no longer passed to
the TL).
