Filter events on event connection

Currently if two triggers of the same connection type need to trigger on
different events it's not possible to do so since the events are never
filtered on which connection they came from.

For example with the following setup where gerrit-org-1 only wants to
trigger on changes to 'master' and gerrit-org-2 only wants to trigger on
changes to 'develop' they will instead both trigger on 'master' and
'develop'since the events are never filtered on which connection they
came from.

- pipeline:
    name: check
    trigger:
      gerrit-org-1:
        - event: patchset-created
          branch: 'master'
      gerrit-org-2:
        - event: patchset-created
          branch: 'develop'
