[FEATURE] Add CrayFits to Crayfish

[rosiel]

Overview of feature request

UPEI's Robertson Library has been holding onto the code for Crayfits. It is currently being installed in both provisioning systems, ISLE-DC and Playbook.

We propose to contribute the code of CrayFits to Islandora, to live within the Crayfish repository.

This would be accompanied by:

• instructions for existing sites to update Crayfish and remove the separate CrayFits service (both on ISLE and Playbook
• an update to Islandora to include the repository known as islandora_fits as a submodule of Islandora (ticket)
• an update to the Playbook to not install the separate repositories (Crayfits/islandora_fits), and to configure/use the code within Crayfish/Islandora
• an update to ISLE to do the same

Any related open or closed issues to this feature request?
