Subject: Add support for new ipaRangeType attribute

Recent versions of FreeIPA support a range type attribute to allow
different type of ranges for sub/trusted-domains. If the attribute is
available it will be used, if not the right value is determined with the
help of the other idrange attributes.

Fixes https://fedorahosted.org/sssd/ticket/1961
