[New: openFATE 309058] Support patterns a build dependencies

Feature added by: Adrian Schröter (adrianSuSE) Feature #309058, revision 1 Title: Support patterns a build dependencies Buildservice: Evaluation Priority Requester: Mandatory Projectmanager: Mandatory Requested by: Adrian Schröter (adriansuse) Description: Esp. for kiwi image builds we need to support also patterns as build dependencies. This may be done together with fate #309057 (Generate patterns out of product descriptions), but we could also already support it with current pattern support of OBS. That would mean we need to generate the patterns from past products also as OBS pattern. -- openSUSE Feature: https://features.opensuse.org/309058
