Cycling api-x stack and loading microservices in post-install

[dannylamb]

GitHub Issue: Part of Islandora/documentation#739 and Islandora/documentation#738

What does this Pull Request do?

Jiggles the cable on Api-X to get it to start up right on our single server setup. It also loads our Crayfish microservices into Api-X so that they're available to us.

How should this be tested?

• Pull in these changes using git
• vagrant up
• Ingest a Tiff (you can use Drupal or go to Fedora directly)
• Issue a HEAD request against the Tiff to get its service doc in the link headers. For example, my tiff was located at http://localhost:8081/fcrepo/rest/eb/97/cf/93/eb97cf93-f162-4981-8007-f83319848275, so I did this:

daniel@daniel-Latitude-3560:~/Code/Environments/claw_vagrant$ curl -I http://localhost:8081/fcrepo/rest/eb/97/cf/93/eb97cf93-f162-4981-8007-f83319848275

• Then issue a GET request on the service doc (it's the link header of rel=service)

You should see three service instances. One for ocr, convert, and identify.

So this worked for me, but also the issue-640 PRs worked for me out of the box.

So I'm not sure if we want to put this in and then maybe try removing it later

or

wait until after the sprint and push in 640 and see if it solves the issue and hold on to this PR

or

just push this in and put issue-640 over top.
