The format of `san` parameter was changed from a string to the dictonary
of lists.
Example:
```
san:
dns:
- "{{ ansible_facts['hostname'] }}"
ip:
- "{{ management_address }}"
uri: []
other: []
```
It will be extremely useful when adding new backends to PKI role.
For example, hashi_vault requires to define dns/ip/uri and other sans in
completely different variables, while in standalone plugin we need to
combine all of them in a string.
But generating a string in required format from the above dict is way
easier than generating a dict in an expected format based on a string.
