Create an initial solr edges.tgz for our association index

[kevinschaper]

• [X] Use the relation-graph tsv branch to generate closures (starting with just subclass of to start)
• [X] Create node-names tsv file (full nodes file does not load well into BigQuery, plus we just need names for now)
• [X] Join node-names.tsv, relations.tsv with edges.tsv to produce a tsv with subject & object closures
• [ ] Add subject & object name closures
• [X] Create initial linkml-solr schema
• [ ] Load into solr with mounted data directory
• [ ] Create tgz and upload to bucket

Moving this to the icebox for now, I'm hoping to get back to Solr soon
