When Nova and/or Cinder are using Ceph as backend, qemu will need
to open a connection and two threads for each and every Ceph OSD.
Since all connections occur in the same qemu process, this may result
in hitting default max open files limit.
Thus in case of more then 10 volumes are attached
to the same instance and are used actively can end up in blocked
IO operations inside VMs.
We increase these limits by default when RBD backend is used.

As per the community goal of migrating the policy file
the format from JSON to YAML[1], we need to replace policy.json to
policy.yaml and remove deprecated policy.json.
config_template has been choosen instead of the copy, since it can
properly handle content that has been lookuped.
We make a separate task not to restart service when it's not needed.

It appears that usage of static imports is not allowed inside dynamicaly
included task. This results in ansible error which hasn't been catched
by CI for some reason.
Currently setup ends up with the following error for LXC deployments [1]

Tags are working differently with includes vs imports, so we should
respect that and use appropriently.

OS specific variables files are generalised where possible

Currently, the list of supported vGPUs is populated automatically
within the Nova playbook when the /sys/class/mdev_bus folder is
present. This will populate the `enabled_vgpu_types` variable with
the full list of vGPUs that are supported by default, with only
the first one listed being used.
This change provides the ability to define a new variable
`nova_enabled_vgpu_types` that will populate the enabled_vgpu_types
config option. It also adds the ability to map vgpu types to PCI
addresses in line with Ussuri updates to provide multi-vGPU support.

nova_libvirt_images_rbd_pool is a string, so applying bool filter always
results to false, which ends up in incorrect behaviour and nova does
not use ceph storage for ephemeral drives.

Since we copy all release notes to the integrated repo there is not need
in publishing release notes for each repository. We should only verify their
validity and linting.

When you change policy on a running system, you expect that
this operation will be fast enough and only change policy.json
Without this tag you have to run whole role.
Use tag: nova-policy-override to just override policy.json
Added nova-config and services restart to the same task

Instead of overriding each service separatelly it might make
sense for deployers to define some higher level variable that
will be used first or fallback to default variable.

Since libvirt 5.7 we should not use traditional mode. Instead systemd
mode should be choosen. Sockets are provided by libvirt package.
We just need to conditionally enable or disable them.
As addition we changed nova_libvirtd_listen_tls to 0 by default
because listen_tls requires certificate to be provided which is not
the case in the current role state. So we also fix behaviour of the role
when nova_libvirtd_listen_tls is 1, supposing that deployer has manually
distributed certificates across compute hosts.

UPPER_CONSTRAINTS_FILE is deprecated and TOX_CONSTRAINTS_FILE is
the new environment variable name that replaces it [1].
This allows to use upper-constraints file as more
readable way instead of UPPER_CONSTRAINTS_FILE=<lower-constraints file>.

ceph_client role checks length of the `openstack_service_venv_bin` variable
to determine if libraries symlinking into venv should occur. So for
distro path this should be empty string as no symlinking should be done.

While we don't test all these virt types, see no reason in explicitly
limiting list of them, considering that they are supported by nova and
libvirt itself [1]

We use the same condition, which defines against what host some "service"
tasks should run against, several times. It's hard to keep it the same
across the role and ansible spending additional resources to evaluate
it each time, so it's simpler and better for the maintenance to set
a boolean variable which will say for all tasks, that we want to run
only against signle host, if they should run or not now.
