Cédric Jeanneret d77fe55516 Ensure SELinux context persist across restorecon and reboot
Until now, we only relied on the ":z" flag in order to set container
volumes label to container_file_t.
While it works fine, it has multiple issues:
- if an operator runs a restorecon, it might break the container service
- if an SELinux related package is updated, it might reset the label,
  and break the container service
- it requires a container stop&start to reset the label to the expected
  value
- in case of deep tree or huge amount of file, relabelling takes time

This change ensures the system sets the expected context on the specific
locations, instead of following the content of selinux-policy-targeted
rulesets.

It has an equivalent for some locations in tripleo-ansible repository:
https://review.opendev.org/c/openstack/tripleo-ansible/+/782393

Note about swift locations:
Since openstack-selinux already sets fcontext rules for, at least, once
swift location, we can't override it here. The following
openstack-selinux patch is being pushed in order to work around this
specific case:
