When migrating/resizing VM to destination
host that has VIF type difference from source VIF
type, it fails due to exception in unplugging
VIF on source host after user perform a confirmation
action.
This change unplugs the vifs in resize_instance and
wraps the call to unplug in confirm with an try except
block. the call to unplug_vifs in confirm is not removed
to support rolling upgrades but a todo is added to remove
it after the Wallaby release.

In I147bf4d95e6d86ff1f967a8ce37260730f21d236 we added a new argument for
the rebuild_instance() RPC method. Unfortunately, we missed to that it
needs to be optional for older versions.
Adding a default none value for it so rolling upgrades would work.

Nova services only support computes that are not older than
the previous major release. This patch introduces a check in the
service startup that prevents staring the service if too old computes
are detected.

At start up of nova-compute service, the PCI stat pools are
populated based on information in pci_devices table in Nova
database. The pools are updated only when new device is added
or removed but not on any device changes like device type.
If an existing device is configured as SRIOV and nova-compute
is restarted, the pci_devices table gets updated but the device
is still listed under the old pool in pci_tracker.stats.pool
(in-memory object).
This patch looks for device type updates in existing devices
and updates the pools accordingly.

During the implementation of blueprint request-filter-image-types,
I left a FIXME to follow-up and add an ability for an operator to
configure compute nodes to not expose image formats that they *can*
support, for situations where they may not be desired. Consider a
remote compute node which *can* support raw images, but for which
you want to require that the user use qcow2 for transfer efficiency.
This adds a new compute-level config option which allows excluding
image types, which will be filtered out of the traits list in a
general way, to avoid having to honor the list in each driver.

Ia18e9be4d07b732afd9db0007c541253f3cdaf82 bumped these versions in
Ussuri and while it's late in the Victoria cycle we now need to do the
same. Based on the LibvirtDistroSupportMatrix wiki page [1] the
following versions have been selected for the next min versions during
the Wallaby release:
NEXT_MIN_LIBVIRT_VERSION = (6, 0, 0)
NEXT_MIN_QEMU_VERSION = (4, 2, 0)
MIN_QEMU_VTPM is removed as part of this patch as it also requires
changes to functional tests that would otherwise fail.
Follow up patches will remove the following constants after this change:
- MIN_LIBVIRT_FILE_BACKED_DISCARD_VERSION
- MIN_{LIBVIRT,QEMU}_NATIVE_TLS_VERSION
- MIN_LIBVIRT_BETTER_SIGKILL_HANDLING
- MIN_LIBVIRT_VIDEO_MODEL_VERSIONS
- MIN_{LIBVIRT,QEMU}_PMEM_SUPPORT
This change depends on the following devstack change that introduces the
use of the Train UCA on Bionic nodes, allowing us to bump versions here
ahead of a move to Focal.

When vif_type="tap" (such as when using calico),
attempting to create an instance using an image that has
the property hw_vif_multiqueue_enabled=True fails, because
the interface is always being created without multiqueue
flags.
This change checks if the property is defined and passes
the multiqueue parameter to create the tap interface
accordingly.
In case the multiqueue parameter is passed but the
vif_model is not virtio (or unspecified), the old
behavior is maintained.

For attach:
* Generates InstancePciRequest for SRIOV interfaces attach requests
* Claims and allocates a PciDevice for such request
For detach:
* Frees PciDevice and deletes the InstancePciRequests
On the libvirt driver side the following small fixes was necessar:
* Fixes PCI address generation to avoid double 0x prefixes in LibvirtConfigGuestHostdevPCI
* Adds support for comparing LibvirtConfigGuestHostdevPCI objects
* Extends the comparison of LibvirtConfigGuestInterface to support
macvtap interfaces where target_dev is only known by libvirt but not
nova
* generalize guest.get_interface_by_cfg() to work with both
LibvirtConfigGuest[Inteface|HostdevPCI] objects

Default value of 'CONF.oslo_policy.policy_file' config option
has been changed from 'policy.json' to 'policy.yaml'. If new default
file 'policy.yaml' does not exist but old default 'policy.json' exist
then fallback to use old default file.
An upgrade checks is added to check the policy_file format and
fail upgrade checks if it is JSON formatted.
Added a warning in policy doc about JSON formatted file is deprecated,
also removed all the reference to policy.json file in doc as well as
in tests.

In the rocky cycle nova was enhanced to support the multiple
port binding live migration workflow when neutron supports
the binding-extended API extension.
When the migration_data object was extended to support
multiple port bindings, populating the vifs field was used
as a sentinel to indicate that the new workflow should
be used.
In the train release
I734cc01dce13f9e75a16639faf890ddb1661b7eb
(SR-IOV Live migration indirect port support)
broke the semantics of the migrate_data object by
unconditionally populating the vifs field
This change restores the rocky semantics, which are depended
on by several parts of the code base, by only conditionally
populating vifs if neutron supports multiple port bindings.

The 4.14 kernel is sufficiently old in the tooth (Ubuntu 18.04 uses
4.15, RHEL 7.x has likely backported the fixes) that there are likely
not a great deal of users that could still use this broken feature if
they wanted to. Drop support for it almost entirely, retaining only a
warning to prevent accidental use.

Only allow one detach/attach at a time with the same pattern instance-port_id
in order to avoid race condition when multiple detach/attach are run
concurrently.
When multiple detach run concurrently on a specific instance-port_id,
manager consider many of them as valid because info_cache still contains
the port and info_cache is refreshed only once the first request complete.
So during this gap of time, while the first request accomplishes the task,
all subsequent requests are destined to fail and log a warning [1] in
different location of code, depending on the outcome of the first request.
The Issue is that all those caught requests finally run a
deallocate_port_for_instance which will unbind the port.
This may cause a race condition, because a successful attach can pass between
those unbind, and be silently unbound, resulting in an infrastructure/DB
inconsistency.

on the guest.'

Previously, the default value of num_retries for glance is 0.
It means that the request to glance is sent only one time.
On the other hand, neutron and cinder clients set the default
value to 3.
To align the default value for retry to other components, we
should change the default value to 3.
