This bug is just for fetching data needed to build "preview" WorkflowRuns (bits
from the karXML, not the kars or entire karXMLs). I get all records in one
query to metacat. I did some quick timing tests of WRM with kepler-dev (there
are a few reasons why these shouldn't be considered exact, but they give a good
rough idea) :

The ~30s that it currently takes to show all ~131 preview runs for a first time
switch of WRM to kepler-dev breaks down roughly:
1) "anon" authentication via kepler gui: ~6s
2) query to fetch all data needed to build workflowRuns: ~4s
3) locally building runs, writing to provenance and tracker file: ~17s

For a subsequent Refresh action:
1) ~0s (already authenticated)
2) ~3s
3) ~0s

So I'll look into improving #3, the big cost must be the write actions.
