pytest/pluggy conflict on Caracal/Jammy

[Dmitriy Rabotyagov]

In UCA for Bobcat python3-pytest was built and shipped from UCA, while python3-pluggy was present only on universe:

root@aio1:/home/ubuntu# apt-cache policy python3-pytest
python3-pytest:
  Installed: (none)
  Candidate: 7.4.0-2~cloud1
  Version table:
     7.4.0-2~cloud1 500
        500 http://ubuntu-cloud.archive.canonical.com/ubuntu jammy-updates/bobcat/main amd64 Packages
     6.2.5-1ubuntu2 500
        500 http://nova.clouds.archive.ubuntu.com/ubuntu jammy/universe amd64 Packages
root@aio1:/home/ubuntu# apt-cache policy python3-pluggy
python3-pluggy:
  Installed: (none)
  Candidate: 0.13.0-7.1
  Version table:
     0.13.0-7.1 500
        500 http://nova.clouds.archive.ubuntu.com/ubuntu jammy/universe amd64 Packages
root@aio1:/home/ubuntu#

For Caracal situation reverted, which results in installation conflict "out of the box":

root@aio1 /opt/openstack-ansible # apt-cache policy python3-pytest
python3-pytest:
  Installed: (none)
  Candidate: 6.2.5-1ubuntu2
  Version table:
     6.2.5-1ubuntu2 500

root@demo /opt/openstack-ansible # apt-cache policy python3-pluggy

The following information may help to resolve the situation:

The following packages have unmet dependencies:

My blind guess would be, that relevant python3-pytest version is simply missing for Caracal UCA and should be re-added there to avoid the conflict.
