• We need to add create a class that can track the checks and privileges made by AuthorizationSession and a class for IDL to store its contract
• AuthorizationSessionImpl will be augmented with this class in a later ticket
• IDL will write this contract into a member variable of the generated command class

This class should have at minimal the following information to support its needs

• Constructor(initializer_list<acess_checks>, initializer_list<privileges>) - to be used to IDL to generate code
• Stores a stdx::unordered_map<ResourcePattern, ActionSet>
• Stores a bitset for all the access checks in AuthorizationSession except for privilege checks
  • Note the privilege check isAuthorizedForAnyActionOnAnyResourceInDB - counts as a access check
  • Has getters/setters
  • Add a method to verify a contract is a subset of another
  • Naive O(N^2) algo should be fine since number of checks is usually 1-3 except for agg

C++ Unit Tests to add

• Validate a none generated contract
• Validate a simple generated contract with a privilege
• Validate a simple generated contract with a check
• Validate a complex generated contract with a mix of privileges and checks
