Remove regions From all Program interactions

[joneubank]

The program data model is being updated to have data centers instead of regions. We need to find all UI references to regions and remove this code from the UI.

The most important interaction with regions is in the Create Program and Update Program screens. There may be other uses across the program submission screens.

Detailed Description

• Create Program / Update Program form
  • Remove regions form input
  • Remove regions references in form data validation
  • Remove regions from API request sent to create/update form
• Remove regions from any GraphQL requests being made to gateway
• Search and find all regions references and remove them.
