Fixes for CentOS 8.3

* 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.
