adding MODS form and integration to 7.x-1.4 branch

This request adds a default MODS form to the Collection Solution pack. After specifying the label and PID for the collection, the user is presented with a MODS form to fill out.  I think this fills a gap - collection objects can now be described with their own metadata. Those descriptions can be indexed and exposed in the interface.
I was hoping it would be handled in https://jira.duraspace.org/browse/ISLANDORA-1042
