Title: Adding support to get upstream jobs and builds

In the case Jenkins has downstream/upstream jobs, this change adds more flexibility to handle them.
It is just adding some methods to get the upstream job or/and the master job as long as their corresponding build.
If the build doesn't have any upstream or master job/build it doesn't fail, it just return None
