Allow omitted objects to be included with a new custom qualifier

[gwardwell]

Description

When a custom nodeQualifier is provided, it is possible to completely omit an entity from the FROID schema. Since this may not always be the desired behavior, this PR adds a new optional qualifier to re-evaluate omitted entities to determine if they should be included in the FROID schema. We need to do it this way because we have to build the list of passing entities before we can reevaluate whether the omitted entities should actually be included in the FROID schema.

The tests contributed by this PR illustrate the changes in behavior with and without the new qualifier being provided.
