add minerva display app for covid

[hexylena]

What did you do?

• Added covid19 pathway map display application

Why did you make this change?

This is a followup to BioHackathon2020 where we worked on the integration of pathway analysis in Galaxy.

How to test the changes?

• Instructions for manual testing are as follows:
  1. load a tabular dataset (mine was on test.usegalaxy.eu which is currently down or I'd share)
  2. correct dbkey
  3. click viz and be taken to a nice pathway diagram showing enrichment.

For UI Components

• I've included a screenshot of the changes

@bgruening what's the dbkey for covid? This feels wrong but can't tell.
