common: add centos8 support

Ceph octopus only supports CentOS 8.

This commit adds CentOS 8 support:
  - update vagrant image in tox configurations.
  - add CentOS 8 repository for el8 dependencies.
  - CentOS 8 container engine is podman (same than RHEL 8).
  - don't use the epel mirror on sepia because it's epel7 only.
