Write VPDU configuration in marsdb by vivian again
This change reverts 2 commits where the VPDU configuration was moved from vivian to the executor/ansible. This was problematic for two reasons:
- The changes in mars.py from 291fd40b were in the way of getting a dynamic configuration for the PDU in marsdb. This is required to be able to set/remove reserved ports in a PDU.
- Having the VPDU configuration setup up by the executor was getting in the way of the services booting. When reverting these 2 commits I was finally able to get vivian working directly out-of-the-box without all the issues with the services influxdb/minio/executor !
Not everything is great, while testing, this issue https://gitlab.freedesktop.org/mupuf/valve-infra/-/issues/85 re-appeared. So that issue should be re-opened after accepting this MR and I'll work in a fix.
