This patch adds the image_meta used to launch an instance to its
libvirt domain metadata.
Nova exposes the image_meta structure when publishing
instance notifications. Downstream services that consume these
notifications such as Ceilometer use this to provide metadata about
the image originally used to create an ephemeral instance or
instance boot volume.
Ceilometer also polls the running instances using the Compute Agent
by reading the metadata of active instances from the libvirt socket.
Adding the data stored in image_meta to the libvirt metadata allows
Ceilometer to discover and expose the actual image metadata used to
launch instances using its compute pollsters, without performing
additional API queries to Nova, Cinder and Glance to get this
information (and even if that was done, it could be different to what
is actually running if images are updated after the fact).
To match the existing image_meta definition from Nova notifications,
depending on the type of instance, the behaviour of the metadata is:
* Instance built from image
=> UUID set for image, image metadata added to the XML
* Instance launched from volume built from image
=> UUID empty, volume image metadata added to the XML
* Instance launched from volume NOT built from image
=> UUID empty, no attributes from image meta defined

This change adds the the following new information to the existing
flavor metadata structure in the libvirt guest XML:
* Flavor ID
* Extra specs
Downstream clients that query this guest XML such as Ceilometer
may also require this information. If it's not defined in this
metadata, clients are forced to perform a Nova API query just
to fetch this additional information.
This change should almost eliminate the need to perform such
API queries.

Nova adds the temporary shelved image ID to libvirt metadata
when unshelving image-backed instances. This is corrected when
the instance is cold restarted, resized or migrated but causes
issues for other services such as Ceilometer which rely on this
data being correct.
This patch ensures the correct image ID is set in the libvirt
domain metadata when image-backed instances are unshelved.

Keystone project manager role can be used for the project-level
management APIs. Nova introduced the manager role in policy
defaults.
To introduced the manager role, we need to make migrations
policies more granular. Adding the separate policies for host
related operation allow us to open the migration operations
to project manager role. Existing policy is checked if migration
without specifying host and new policy is checked if host is
specified. Same will be applied to list migrations, new policy
will control to return the host info.

The libvirt driver now automatically enables autodeflate and
freePageReporting attributes for virtio memory balloon devices.
The autodeflate feature allows the QEMU virtio memory balloon
to release memory before the Out of Memory killer activates.
The freePageReporting feature enables returning unused pages
back to the hypervisor for use by other guests or processes,
improving overall memory efficiency on compute hosts.
These features are always enabled when a memballoon device is
configured, requiring no additional configuration from operators.

The _create_ephemeral() method is responsible for creating ephemeral
disks with image type "raw" and formatting them with mkfs. In the case
of [libvirt]images_type "qcow2", _create_ephemeral() will create
backing files.
Currently we are not using a consistent naming convention for choosing
the filesystem label for ephemeral disks. When we create a server for
example, we go through the disks and label them "ephemeral0",
"ephemeral1", "ephemeral2", etc.
When we hard reboot a server, there is a check to create missing
backing files and if so, a new backing file will be created but instead
of being labeled "ephemeralN" the code attempts to label them with the
name of the backing file itself for example "ephemeral_1_40d1d2c". This
will fail if the filesystem used for ephemeral disks has limitations on
the length of filesystem label names (VFAT, XFS, ...). For example:
mkfs.vfat: Label can be no longer than 11 characters
This adds a helper method for obtaining ephemeral disks filesystem
label names and uses it the same way in the few places fs_label is
specified.

The tl;dr is to 1) avoid trying to disconnect volumes on the
destination if they were never connected in the first place and
2) avoid trying to disconnect volumes on the destination using block
device info for the source.
Details:
* Only remotely disconnect volumes on the destination if the failure
was not during pre_live_migration(). When pre_live_migration() fails,
its exception handling deletes the Cinder attachment that was created
before re-raising and returning from the RPC call. And the BDM
connection_info in the database is not guaranteed to reference the
destination because a failure could have happened after the Cinder
attachment was created but before the new connection_info was saved
back to the database. In this scenario, there is no way to reliably
disconnect volumes in the destination remotely from the source because
the destination connection_info needed to do it might not be
available.
* Due to the first point, this adds exception handling to disconnect
the volumes while still on the destination, while the destination
connection_info is still available instead of trying to do it
remotely from the source afterward.
* Do not pass Cinder volume block_device_info when calling
rollback_live_migration_on_destination() because volume BDM records
have already been rolled back to contain info for the source by
that point. Not passing volume block_device_info will prevent
driver.destroy() and subsequently driver.cleanup() from attempting to
disconnect volumes on the destination using connection_info for the
source.

The nova debuger functionality was intended
to help debugging running process however it has
never been reliable due to our use of eventlet and is generally
not required when not using eventlet. I.e. you can just
run the nova console-scripts form a debugger or add pdb
statements as required.
As part of the eventlet removal the debugger functionality is
removed given its untested and undocumented.

The request_specs_dict in the _list_view is initialized as a
defaultdict object in order to return empty string as default.
But the request_spec_dict is replaced with a normal dict object in
the v2.96 microversion, then if server list and RequestSpec missmatch
happens by any reason, the List Server API and the List
Server Detail API hit 500 Internal server error because of key error.
This commit updates the req_spec_dict to use normal dict object, then
it returns sentinel object if there is no appropriate
request_spec object.

is applied to the init_applciation function in our
common wsgi_app module.

The stats module uses the _find_pool() call to find a matching pool for
a new device or a device that is being deallocated. If no existing pool
matches with the dev then then a new pool is created for it. The
pool matching logic was faulty as it did not remove all the metadata
keys from the pool like rp_uuid. So if the dev did not have that key but
the pool did then the dev did not match.
On the other hand the PCI allocation logic (when PCI in Placement is
enabled) assumed that devices from a single rp_uuid are always in a
single pool. As this assumption was broken by the above bug the PCI
allocation blindly tried to allocate resources for an rp_uuid from each
matching pool causing overallocation.
The main fix in this patch is to ignore the metadata tags in
_find_pool(). But also two safety net are added to the allocation logic.
The logic now asserts that the assumption is correct and if not (i.e. it
found multiple pools with the same rp_uuid) then it bails out. It also
does not ever blindly allocate the same rp_uuid request from multiple
pools.

It also updates the _live_migration_operation() function, particularly
the get_updated_guest_xml() function, to map source PCI addresses
to destination addresses in the destination XML file, using the data
provided by the LiveMigrateData object.
