Either the vendor_id and product_id needs to be set or the
resource_class needs to be set in each alias. This is now validated when
the alias is parsed to avoid late failure during placement
allocation_candidates query.

Document and the limitation of the PCI in Placement feature that it
does not support [pci]alias configuration where the name of the alias is
repeated. E.g.
[pci]
alias = { "name": "vf1", "product_id":"10ca", "vendor_id":"8086", "device_type":"type-VF"}
alias = { "name": "vf1", "product_id":"f000", "vendor_id":"8086", "device_type":"type-VF"}
This would mean the alias vf1 can be fulfilled from devices with product
id 10ca OR f000. However this OR relationship cannot be encoded to a
single Placement allocation query as Placement does not support
requesting alternative resource classes for a request[2].
This limitation was encoded in the original PCI in Placement
implementation[1] but we missed to mention it in the doc.
This is now fixed.

When I069879a333152bb849c248b3dcb56357a11d0324 merged in Caracal, we forgot
to add documentation for the SR-IOV GPU caveat fix.
Also, given the new max_instances option was dynamic, we can't even see it
in the configuration list, so actually none of our operators can know that we
fixed it and how to do it 🤦

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.

This adds config options for unified limits quotas that allow
admin/operators to specify which resources they will require or ignore
to have unified limits set in Keystone.
The options are only used when ``[quota]driver`` is set to
``UnifiedLimitsDriver``.
When the resource strategy is set to 'require' (the default), the
resource list will represent the resources that are required to have a
registered limit set in Keystone.
When the resource strategy is set to 'ignore', the resource list will
represent the resources that will be ignored for quota enforcement if
they do not have a registered limit set in Keystone.
