This patch introduces an optional backend encryption for the Barbican
API service. 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 Barbican service.

flake8 new release 3.8.0 added new checks and gate pep8
job start failing. hacking 3.0.1 fix the pinning of flake8 to
avoid bringing in a new version with new checks.

Though it is fixed in latest hacking but 2.0 and 3.0 has cap for
flake8 as <4.0.0 which mean flake8 new version 3.9.0 can also
break the pep8 job if new check are added.

To avoid similar gate break in future, we need to bump the hacking min
version.

Ansible 2.9.8 includes a regression on the fileglob plugin [1] that
causes the HAProxy role to fail.

This change blacklists Ansible 2.9.8 to work around the issue.

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

    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.

The removal of Kolla Ceph deploy [1] broke gnocchi & external Ceph
integration - the variable gnocchi_pool_name is referenced in the config
template, but should now be ceph_gnocchi_pool_name.

This change fixes the issue.

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.

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."
