Add version 4.2 to all existing migrations DB schema generated by a migration may look different in rails 4 and 5 (because rails 5 may use different default values). For this reason it's important to explicitly set for which rails version a migration was written for.

Add foreign key on trigger requests I started out as I missed the foreign key on ci_triggers and projects. However, it seemed Yorick caught this already on gitlab-org/gitlab-ce!9388. Still I found a missing foreign key, between the trigger requests and triggers. This commit adds it, and removes the depend: :destroy on the Rails model Ci::Triggers 2017-04-07 13:56:08 +00:00			`include Gitlab::Database::MigrationHelpers`
