Align sample Descriptors with Types and remove non-viable sample Descriptors

Summary of outcomes for Data Standard 2.1

• Problem Addressed: There are some non-viable sample descriptor values that should be removed. Additionally, identified a DisciplineMap type value to be added from sample xml file.
• High-level Reasoning: In many case, our attempts to align sample descriptors and types exposed weaknesses in sample descriptors, and in some cases non-viable lists of descriptor values (e.g. descriptor lists that are obviously non-comprehensive or sufficient). In such cases, sample descriptors need to be removed, or other changes made.
• Changes Made: Added "No Action for incident" to DisciplineMap type; Removed extra sample descriptor values where map types didn't exist (see attached); Corrected sample descriptor "Other" value in SchoolFoodServicesEligibilityDescriptor to "Unknown"
