This reverts commit f45f925e5e1dbfec627345868d0dd56abc77c4f1, reversing
changes made to 90c07943e4173ef8e32dae5087203f5a712f8077.
This was too early, need to check for incubator
...issues as reported by Travis. Add requirement for parent and child host
fields when setting up a Dependency Object (these fields are not necessarily
needed for Templates or Apply Rules). Renamed new table field to
'parent_service_by_name'... which is a bit more descriptive or what that
field is intended for.
