due to bug #1940425 where ml2/ovn is not correctly configuring the
active status on trunk port we see test_live_migration_with_trunk
fail more often then not.
This was previously disbaled in tempest and then fixed in neutorn.
the tempest skip was then reverted and so was the neutron fix as
it broke somethign else... so this is failing in our gate again.
This change skips test_live_migration_with_trunk on all jobs that
are using ml2/ovn but keeps it enabled on the hybrid plug job
which uses ml2/ovs.

This change refactors prvisep util test cases to account for the
fact that oslo.log now conditionally uses an internal pipe mutex
when logging under eventlet.
This was added by Iac1b0891ae584ce4b95964e6cdc0ff2483a4e57d
which is part of oslo.log 5.3.0
As a result we need to mock all calls to oslo.log in unit tests
that are assertign if os.write is called. when the internal
pipe mutex is used oslo.log calls os.write when the mutex is
released.

We agreed last cycle on the support envelope.
Pre-RC1, we need to add a service version in the object.
Post-RC1, depending on whether it's SLURP or not SLURP, we need to bump
the minimum version or not.
This patch only focuses on pre-RC1 stage.
Given Caracal is SLURP, we won't need any post-RC1 patch for updating the min
that will stay to be Antelope.
HTH.

This addresses comments from code review to add handling of PCPU during
the migration/copy of limits from the Nova database to Keystone. In
legacy quotas, there is no settable quota limit for PCPU, so the limit
for VCPU is used for PCPU. With unified limits, PCPU will have its own
quota limit, so for the automated migration command, we will simply
create a dedicated limit for PCPU that is the same value as the limit
for VCPU.
On the docs side, this adds more detail about the token authorization
settings needed to use the nova-manage limits migrate_to_unified_limits
CLI command and documents more OSC limit commands like show and delete.

Many bugs around nova-compute rebalancing are focused around
problems when the compute node and placement resources are
deleted, and sometimes they never get re-created.
To limit this class of bugs, we add a check to ensure a compute
node is only ever deleted when it is known to have been deleted
in Ironic.
There is a risk this might leave orphaned compute nodes and
resource providers that need manual clean up because users
do not want to delete the node in Ironic, but are removing it
from nova management. But on balance, it seems safer to leave
these cases up to the operator to resolve manually, and collect
feedback on how to better help those users.

When people transition from three ironic nova-compute processes down
to one process, we need a way to move the ironic nodes, and any
associcated instances, between nova-compute processes.
For saftey, a nova-compute process must first be forced_down via
the API, similar to when using evacaute, before moving the associated
ironic nodes to another nova-compute process. The destination
nova-compute process should ideally not be running, but not forced
down.

On reboot, check the instance volume status on the cinder side.
Verify if volume exists and cinder has an attachment ID, else
delete its BDMS data from nova DB and vice versa.
Updated existing test cases to use CinderFixture while rebooting as
reboot calls get_all_attachments

Ironic in API 1.82 added the option for nodes to be associated with
a specific shard key. This can be used to partition up the nodes within
a single ironic conductor group into smaller sets of nodes that can
each be managed by their own nova-compute ironic service.
We add a new [ironic]shard config option to allow operators to say
which shard each nova-compute process should target.
As such, when the shard is set we ignore the peer_list setting
and always have a hash ring of one.

As part of the move to using Ironic shards, we document that the best
practice for scaling Ironic and Nova deployments is to shard Ironic
nodes between nova-compute processes, rather than attempting to
user the peer_list.
Currently, we only allow users to do this using conductor groups.
This works well for those wanting a conductor group per L2 network
domain. But in general, conductor groups per nova-compute are
a very poor trade off in terms of ironic deployment complexity.
Futher patches will look to enable the use of ironic shards,
alongside conductor groups, to more easily shard your ironic nodes
between nova-compute processes.
To avoid confusion, we rename the partition_key configuration
value to conductor_group.

We leak due to running background operations like server create, rebuild
and in one case a sleeping claim. So this patch removes the leaks by
making sure that the background operations stop before the test
finishes.
As there is no more leak in functional test too this patch makes the
leak an error there too.
Change-Id: I6905999050e8d09b772837034a212c534e9c3226
The leak tests just start a server create and the finish so I think
the actual conductor thread leaks. If I add a bit of sleep to the end of
these test cases then the leak disappears. Unfortunately adding the
sleep at the greenpool fixture does not have this effect. So instead I
added delete_server calls to the end of these tests as those are nicer
than sleeps and has the same effect regarding the leak.
We are down to 3 leaking functional test

This change add a global greenpool which is used to manage
the greenthreads created via nova.utils.spawn(_n).
A test fixture is also added to use an isolated greenpool
which will raise an exception if a greenthread is leaked.
the fixture will optionally raise if greenlets are leaked.
This is enabled by unit test by default and is configurable
for functional tests.
This change removes all greenthread leaks from the unit
and functional tests that were detected. 7 functional
tests still leak greenlets but they have no obvious
cause. as such greenlet leaks are not treated as errors
for funtional tests by default. Greenthread leaks
are always treated as errors.
Set NOVA_RAISE_ON_GREENLET_LEAK=1|true|yes when invoking
tox to make greenlet leaks an error for functional tests.
