Bug 1153585 Several plugins added l3 support in the grizzly release. This means that when upgrading from the folsom data model, the relevant data model changes should be applied. In order to do so this patch refactors the initial migration in order to be able to reuse the upgrade_l3 and downgrade_l3 routines. Change-Id: I876f6d637665e10fb09d2084bb8a545ce469fbf3
