Ingest Form with conditional fields

[DonRichards]

The ingest page needs more intuitive grouping and conditional fields.

Grouping

I'm suggesting we group the content to give context. For instance, language is a drop-down in 2 separate locations in the same form.

• Content Model/resource type
• Fields (title, description, etc.)
• Behavior (viewer, parent/member of)
• System level (language, weight, notes, table of contents)

Conditional form fields

Most importantly I think several of these fields need to be hidden when a collection vs a video content model is selected.

Suggested behavior

This will probably be best experienced when both of these suggestions are applied. At the top of the form should be the content model. Once a "content model" is selected, all of the irrelevant fields should be "hidden" as a default to keep the interface clean and intuitive.

This ticket is roughly related to #932

Grouping can be done via https://www.drupal.org/project/field_group, and https://www.drupal.org/project/conditional_fields looks like it will provide a GUI for defining conditional fields.

Hashed this out at the last Islandora 8 call and consensus was to keep all the fields, but disable most of them, leading to a more streamlined default that you can add to from already existing fields.
