Fix run_tests.sh lockutils when run with -d

Change I007bd39e4d9aad7539b4b7389eb5189b5d1f10e2 fixed how the test
runner was called, but did not take into account that a different
command line is used when -d flag is passed to the script. We fix that but
accounting for the lockuitls change even when -d is passed.

Explicity teardown on error in libguestfs setup()

Previously, in the setup method of the libguestfs driver
for Nova's VFS, on an error the handle object was simply
dereferenced (set to None), and then an new error was thrown.
This relied on an implicit close() on the handle being called
by GC.  However, in some cases the setup progresses far enough
that the implicit close is not enough, and leaves an "orphaned"
libguestfs VM.

Now, the teardown() method is called explicitly, which ensures that
no "orphaned" VMs are left around in case of an error.

Fixes the Hyper-V VolumeOpsTestCase base class

The VolumeOpsTestCase base class inherits incorrectly from
HyperVAPITestCase, with the unwanted side effect of executing all
base class tests as well.

This patch generalizes a common base class from HyperVAPITestCase
and fixes the inheritance issue.

Prevent caller from specifying id during Aggregate.create()

The patch is to remove id when it was set before creating an aggregate
in objects, and check if the aggregate exists before it is created.

Related to blueprint icehouse-objects.

VMware: support instance objects

Over the course of Icehouse the instance dictionary has been changed
to an instance object. The patch ensures that the driver functions
receive an instance object as input.

Sync latest config file generator from oslo-incubator

The fix to the config file generator to support lazy messages
is the main addition of interest because it is needed before
lazy messages can be enabled in Nova.

Commits included:

  1a6dfb956 Sanitize FQDN in config generator
  e839886cc Config generator fails with lazy messages
  763eedff6 Fix DictOpt support in config sample generator

Note that these commits do not touch any other files (beyond
oslo testcases).

Partially implements blueprint i18n-messages

xenapi: stop destroy_vdi errors masking real error

We frequently call destroy_vdi in an exception block where we plan to
re-raise the exception.

Should an error occur while destroying the vdi this hides the real error
that caused the problem. To stop this, I have moved those calls to
safe_destroy_vdis and added unit tests to ensure the error from
destroy_vdi does not mask the real issue.

xenapi: changes the debug log formatting

This patch changes the log formatting to use multiple arguments instead
of interpolation.

Note:
It's a matter of performance :
When you do the interpolation in your code, this code will be executed
each time you call the logger (event if the logger or the log level is
not activated).
When you let the logger do the interpolation, it will do the interpolation
only if the logger and log level is activated.

Move vbd plug/unplug into session object

To make it easier not to miss the VBD plug/unplug workaround I have
moved this into the xenapi object, overriding the regular method.

Move xenapi/agent.py to new call_xenapi style

At the same time, we used to call get_record to just fetch the domid,
this is very expensive compared to just call get_domid, so I have moved
towards using the cheaper call, particularly because this is called many
times when booting a server.

Restore get_available_resource method in docker driver

The get_available_resource method, a necessary public
method was marked as private and it snuck through
code review! We caught this with docker-ci, but
only after it was merged.

This patch makes get_available_resource a public
method again, removing the _ prefix.

This is a partial revert for change:

Support configuring libvirt watchdog from flavors

The previous watchdog-related patch only enabled the watchdog
configuration to be set from the image metadata.  Now, the watchdog
can be configured from both the flavor extra_specs as well as the
image metadata, with the latter overriding the former.
