Fix incorrect kwargs 'reason' for HTTPBadRequest

webob.exc.HTTPBadRequest doesn't have attribute 'reason', and its
__init__ method doesn't have such parameter too, so if we use such
kwargs, it will not be accepted by constructor of base class
WSGIHTTPException, then the http response body will format message
using default explanation instead of what we expected.

We should use kwargs 'explanation' instead of wrong 'reason'.

Replaces exception re-raising in Hyper-V

In a few cases in the Hyper-V driver classes, generic exceptions
are getting caught, logged and a domain specific exception is raised.

This creates issues in identifying the exception cause programmatically
(e.g. in unit tests).

This patch enforces the usage of excutils.save_and_reraise_exception()

VMware Driver update correct disk usage stat

The nodes managed by VMware VCDriver driver can have multiple
datastores (disk abstraction) attached to it. The driver currently
reports the disk usage of a datastore that has the largest capacity.
But it doesn't report a consolidated disk usage. As a result, the
node's storage capability is under-reported in many occassions.

This patch fixes this issue by aggregating the disk freespace,
capacity from all attached datastores.

Skip sqlite-specific tests if sqlite is not configured

There are several tests in test_migration_utils which only work if
sqlite is configured for migration tests, but two of them are missing
the conditional checks for skipping the test.

Also renames test_check_shadow_table_with_unsupported_type to
test_check_shadow_table_with_unsupported_sqlite_type since it's specific
to sqlite.

Remove extra space at the end of help string

Extra spaces in help strings break the niceness gate test for
openstack-manuals (see https://review.openstack.org/#/c/77625/1).

This patch removes an extra space to ease the automatic import of config options
in the docs repository.

Prevent thrashing when deploying many bm instances

Nova BM is easily overwhelmed at the moment because it has to convert
every disk image to raw - simply deploying 2 instances at once exceeds
the IOPS on most single disk servers. Avoid this by serialising the
image conversion (which leads to a lower average-time-to-deploy in
nearly all situations).

notifier middleware broken by oslo.messaging

audit middleware in oslo-incubator is incompatible with oslo.messaging.
an oslo.messaging compatible version is available in pycadf library.
remove broken oslo-incubator code in this patch.

also add middleware/request_id to openstack-common.conf so we continue
to pull in request_id middleware but not audit/notifier.

Fixing host_ip configuration help message

The vCenter/ESXi client can only accept a hostname or IP address
and not a URL.  Fix the help message to accurately describe what
kind of address is accepted.

VMware: refactor _get_volume_uuid

It is more efficient to ask vCenter for specific extraConfig property instead
getting all properties and then manually searching the one which is
needed.

Ignore the image name when booting from volume

In 0185d2445 the _run_instance method was changed to acquire the image
metadata from the request_spec instead of glance. This was needed to be
able to get the image_metadata attached to a volume, when booting from
it. That change didn't consider that the image name key is not inherited
when creating a volume from an image and introduced a bug when creating
the usage_info for volume booted instances.

This change fixes this by only attaching the image name to the usage_info
only when booting from an image and not when booting from a volume.

VMware: create datastore utility functions

The patch moves datastore interfaces from vmops and vm_util
to a separate file - ds_util.

This is part of the blueprint vmware-image-cache-management.

In the past the datastore methods would poll the task
to determine that it had completed. This has beem addressed by
making the driver _poll_task return the task information.

The patch set also solves the following bugs by checking if
the FileAlreadyExistsException exception is raised. This could
be due to another process or thread creating the file.
