Other features/fixes

• Fixed bug that was preventing the plan.funder_id from being set to nil
• Added a new app/javascript/src/utils/conditionalFields.js file that allows you to define sets of fields that are hidden/shown. Currently using it to hides/show the Description and Report URL if the ethical issues checkbox is not checked and the Grant and Funding Status fields if no Funder is selected.
• Added grant getter and setter overrides to the Plan model to allow the grant to be loaded and set properly from incoming UI params.
• Added new config settings to allow the Research Domain and Ethical Issues to be enabled/disabled
• Update API V1 to:
  • Use the plan.owner as the data contact if available (otherwise the contributor who is the :data_curator)
  • Include the new ethical_issues fields
  • Include the research_domain as a :keyword
  • include the plan.org as a :dmproadmap_funded_affilaition to deal with scenarios where the plan.org does not match the orgs defined for the owner or contributors
  • include the user eneterd plan.identifier as :dmproadmap_funding_opportunity_number
• Added lots of tests

DB Changes

• Removed old data_contact, principal_investigator, grant_number and funder_name fields from the plans table since they have been replaced with associations to contributors, identifiers and orgs
• Removes the mime_types table which we decided not to use Remove mime type field from the Research Outputs tab #2816
• Add a Rake task rails external_apis:add_field_of_science_to_research_domains that populates the new research_domains table

Looks fine. Like the fact that it can be switched on/off so we can make it live once it suits.
