DTSAM-1037 "Create utility classes to help simplify Drool Judicial Access Profile processing"

Change description

Create utility functions to simplify and standardise elements of the judicial mappings:

• Match on Appointment codes (via enums, including possible multiple values)
• Match on Additional Role codes (via enums, including possible multiple values)
• Appointment Type / Contract Type: utility function to match on Salaried and SPTW together to ensure we always match on both options (i.e. add isSalaired, isFeePaid and isVoluntary)
• Appointment EndDate
• Authorisation EndDate and ServiceCode, wrap existing validate function to allow switch to using an enum with group of codes.

NB: This PR is branched from the ET feature branch in PR: #2477.
