This provides a generic mechanism to include extra files
that you can reference in prometheus.yml, for example:

scrape_targets:
  - job_name: ipmi
    params:
      module: default
    scrape_interval: 1m
    scrape_timeout: 30s
    metrics_path: /ipmi
    scheme: http
    file_sd_configs:
    - files:
      - /etc/prometheus/extras/file_sd/ipmi-exporter-targets.yml
      refresh_interval: 5m

This provides a mechanism to scrape targets defined outside of kolla-ansible.

This allows you to extend lists in yaml config. This is useful, for
example, in prometheus.yml, where it would be nice to be able to
extend the scrape_configs to include exporters that aren't packaged
with kolla-ansible. This would provide a mechanism to do so.

This causes non-local side effects that are hard to track down. E.g:

--- import errors ---
Failed to import test module: tests.test_merge_yaml
Traceback (most recent call last):
  File "/home/will/.pyenv/versions/3.7.7/lib/python3.7/unittest/loader.py", line 436, in _find_test_path
    module = self._get_module_from_name(name)
  File "/home/will/.pyenv/versions/3.7.7/lib/python3.7/unittest/loader.py", line 377, in _get_module_from_name

    from ansible.errors import AnsibleModuleError
ModuleNotFoundError: No module named 'ansible.errors'; 'ansible' is not a package

This `'ansible' is not a package` message occurs because ansible is a Mock.

Nova cells support introduced a slight regression that triggers
odd behaviour when we tried switching to Apache (httpd) [1].
Bootstrap no longer applied permissions recursively to all log
files, creating a discrepancy between normal and bootstrap runs
and also Nova and other services such as Cinder (regarding
bootstrap logging).

This patch fixes it.

Backport to Train.

Not creating reno nor a bug record because it does not affect
any current standard usage in any currently known way.

Note this only really hides (standardizes?) the global issue that
we don't control file permissions on newly created files too well.

This patch introduces an optional backend encryption for Horizon and
Placement services. When used in conjunction with enabling TLS for
service API endpoints, network communcation will be encrypted end to
end, from client through HAProxy to the Horizon and Placement services.

Zun has a new component "zun-cni-daemon" which should be
deployed in every compute nodes. It is basically an implementation
of CNI (Container Network Interface) that performs the neutron
port binding.

If users is using the capsule (pod) API, the recommended deployment
option is using "cri" as capsule driver. This is basically to use
a CRI runtime (i.e. CRI plugin for containerd) for supporting
capsules (pods). A CRI runtime needs a CNI plugin which is what
the "zun-cni-daemon" provides.

The configuration is based on the Zun installation guide [1].
It consits of the following steps:
* Configure the containerd daemon in the host. The "zun-compute"
  container will use grpc to communicate with this service.
* Install the "zun-cni" binary at host. The containerd process
  will invoke this binary to call the CNI plugin.
* Run a "zun-cni-daemon" container. The "zun-cni" binary will
  communicate with this container via HTTP.

Debian defaults to Python2 which is not complete in aarch64 images.
This patch changes CI to always use Python3.

We need to install several Python modules to have working ussuri jobs.

"Failed to import the required Python library (setuptools) on primary's Python /usr/bin/python3."

And then several Python2 ones for train->ussuri upgrade jobs:

"Unable to find any of pip2 to use. pip needs to be installed."

Since haproxy is orchestrated via site.yml in a single play,
it does not need flushing handlers as handlers run will
happen at the end of this play.

Follow-up on [1] "Avoid multiple haproxy restarts after
reconfiguration".

There is no need to duplicate handler name in listen.
The issue was because we had two handlers with the same
name in the same environment.
This causes Ansible not to mark handler as already run.
