Provide support in OpenProject for the native JIRA fields `Resolution` and `Resolution Date`. Begin of the insertion

Suggested solution:

* Map each resolution value to a dedicated closed status in OpenProject e.g.

* (Jira) Status: Done, Resolution: Fixed -> (OpenProject) Status: Done - Fixed

* (Jira) Status: Done, Resolution: Rejected -> (OpenProject) Status: Done - Rejected

* Create a custom field for Resolution Date and store the Resolution Date value in it as is
