Console fact filtering generates queries with many nested loops

Using the "Filter by fact value" feature of the Console creates a poorly performing postgres query that contains a nested loop for each fact.  Here is the explain analyze output for a query filtering on `operatingsystem` and `operatingsystemmajrelease`. Each filter condition is evaluated in a separate nested loop, and this is exacerbated for each added fact.

Conversely, here is the explain analyze output for this equivalent PQL query:

puppet query 'reports [certname, environment, end_time, hash, status, noop, noop_pending, corrective_change, job_id] { inventory { facts.operatingsystem = "CentOS" and facts.operatingsystemmajrelease = "7" } limit 50 order by end_time}' 

The two filters are evaluated in the same step and the query is faster.

In addition to PE-29836, this can result in multiple slowly running queries that can negatively impact performance as a result of using this feature. I'll attach the explain outputs in case they are pruned from the website.
