tdf#102499 (6): Cache OPTIONS if not present or if lifetime different

Add the OPTIONS information and response status code into the cache:
- if the OPTIONS information is already cached, update the cache only
  if the lifetime is different;
- if the OPTIONS information is not cached, cache it.

Add some new functions in DAVOptions to support the change and remove
a function no longer used.
