Problem

Our current /lineage query is a little slow in instances where there are many jobs. When looking at the query plan, lots of the time is spent in the jobs table with the join operation. We are joining on some unindexed fields via the jobs_view query that merges the jobs table and the jobs_fqn table for some semantic simplicity with our data model.

Solution

Adds indices to the fields used we join on inside the lineage query.

Note: All database schema changes require discussion. Please link the issue for context.
