glom_graph.py to rdfpipe conversion

[kfairbanks]

Background

UCO uses a script glom_graph.py. Accidentally re-implements rdfpipe from RDFLib. glom_graph.py should be removed and its usage replaced with rdfpipe.

This is not a change to the ontology, but a change in the tooling. This relieves UCO of technical debt.

Requirements

Requirement 1

Remove references to glom_graph.py and replace them with rdfpipe.

Requirement 2

Any test results that were dependent on glom_graph.py should have the same results when replaced with rdfpipe.
