Auto select fields mapping in import based on the internal field name (ex: estimared_hours, fixed_version, spent_on) or field label (Estimated hours, Version, Date) (#22913).

* mappings are case insensitive
* a field is auto mapped only if there is no mapping setting present for that field
* "Current user" default value for User field when the user has permission to log time for other users is override by the auto mapped column

Patch by Haihan Ji, Yuichi HARADA, and Marius BALTEANU.
