Tox jobs are timing out in CI due to pip dependency resolution
backtracking taking too long. When run locally, pip fails to resolve
dependencies due to upper-constraints now allowing pluggy 1.0.0 [1],
while molecule still depends on pluggy >= 0.7.1, < 1.0. See similar
tripleo bug for more details [2].

Split molecule dependencies in a separate requirements file and remove
upper constraints from its tox environment for now. As a bonus, it
should speed up execution of the jobs due to installing fewer
dependencies.

Stop using upper-constraints when installing docker python library [3].
This part of the commit can be reverted when docker 5.0.2 is in upper
constraints.

Update Kolla inventory template following renaming of haproxy role to
loadbalancer [4]. With the existing template, haproxy/keepalived
containers are not created and service deployment fails while trying to
connect to MySQL using the VIP.

Molecule also needs to be bumped to support Ansible 2.10
lint: section changed in Molecule 3.x - adapted.
molecule-docker added do test-reqs because it code has moved to it from
molecule core
pytest-testinfra and pytest-molecule needed for testinfra tests to work

* Bump stackhpc.libvirt-host to v1.7.1. On seed-hypervisors installed
  using CentOS 8.2 or earlier, interaction with libvirt may fail due to
  libgcrypt being incompatible. See
  https://github.com/stackhpc/ansible-role-libvirt-host/issues/42

* Bump MichaelRigart.interfaces to v1.9.2. The CentOS 8.3 cloud image
  includes an ifcfg-ens3-1 file. See
  https://github.com/michaelrigart/ansible-role-interfaces/pull/93

* Previously a second libvirt daemon was installed by Tenks on the host,
  however changes in libvirt 6.0.0 to separate libvirtd into multiple
  daemons do not allow for customisation of the PID files used by the
  new daemons. This leads to a conflict between the container and host
  daemons. Update the Tenks config to use the containerised Nova libvirt
  daemon. This depends on a change to the stackhpc.libvirt-host role:
  https://github.com/stackhpc/ansible-role-libvirt-host/pull/44

* Not CentOS 8.3 related, but tox jobs are now failing on python
  dependencies. Remove upper limits from docker and paramiko.

* Not CentOS 8.3 related, but Bifrost has enabled authentication by
  default. We are not ready to support this, so override it.

hacking 3.0.1 fix the pinning of flake8 to avoid bringing in a new
version with new checks.

bumping the min version for hacking so that any older hacking versions
which auto adopt the new checks are not used.

The repo is Python 3 now, so update hacking to version 3.0 which
supports Python 3.

Ignore bashate failure on one-liner loops.

Add pcre devel packages to fix failing pep8 jobs.

Documentation build environments use doc/requirements.txt where sphinx
is already present. Use doc/requirements.txt in the pep8 environment
because sphinx is required by sphinx8.

1. Sync sphinx dependency with global requirements. It caps python 2 since
sphinx 2.0 no longer supports Python 2.7.
2. Update some URLs to latest
3. Remove unncessary "=="

We run yamllint with the same configuration in kayobe-config, so we
should catch issues here before they are synchronised.

Hopefully it will help debug ansible 2.3 related issues.

Unit tests can be run via:

tox -e py27

Style checks can be run via:

tox -e pep8
