Handle node and edge properties to ensure biolink compliance

[eKathleenCarter]

these properties are on our edges:
"edge_properties": [
"Homology",
"affinityParameter",
"Combined_score",
"knowledge_level",
"Cooccurance",
"biolink:tmkp_confidence_score",
"ligand",
"stage_qualifier",
"predicate",
"subject",
"p_value",
"qualified_predicate",
"Coexpression",
"Textmining_transferred",
"protein",
"slope",
"frequency_qualifier",
"expressed_in",
"Database",
"sex_qualifier",
"Textmining",
"publications",
"Fusion",
"primaryTarget",
"pubchem_assay_ids",
"FAERS_llr",
"detection_method",
"sentences",
"onset_qualifier",
"affinity_parameter",
"description",
"supporting_affinities",
"Coexpression_transferred",
"tmkp_ids",
"object",
"agent_type",
"NCBITaxon",
"affinity",
"patent_ids",
"aggregator_knowledge_source",
"object_direction_qualifier",
"score",
"Experiments_transferred",
"primary_knowledge_source",
"Experiments",
"Database_transferred",
"drugmechdb_path_id",
"hetio_source",
"complex_context",
"endogenous",
"object_aspect_qualifier",
"species_context_qualifier"
]

they should be biolink compliant
