Explicit definition of `openstack_pki_san` in integrated repository is
reduntant because all service roles using PKI role already have a
`default()` filter applied that matches the value of `openstack_pki_san`
in integrated repo.
Example:
```
placement_pki_san: "{{ openstack_pki_san | default({'dns': [ansible_facts['hostname']], 'ip': [management_address]}) }}"
```
It's not necessary to define `openstack_pki_san` in integrated repo.
This patch removes it. However, it still can be used by the users to
override cert SAN globally for all openstack services.
