Before this change, if a build was triggered by a build trigger that was subsequently deleted, we'd display "Manually triggered" for the build in the UI, even though we have sufficient metadata to show *nearly the same* normal build information. After this change, if we have said trigger metadata, we still display as much as we can.
Fixes https://jira.coreos.com/browse/QUAY-855
This resolves an issue where the custom-git trigger's public facing
schema was not the same as the internal metadata schema. Instead of
breaking users, we rework the internal metadata schema to be the same as
the custom-git JSON schema. This commit also updates everything that
used `metadata.commit_sha` including the test database.
