Task Description

As an AaC Developer, I want to update the core spec of AaC to include constraints, so that I can support converting validators to constraints.

Acceptance Criteria

• [ ] Create a schema definition of Constraint. Similar to current Validation.  https://github.com/DevOps-MBSE/AaC/blob/0b2eb2b419c06f929f072a24ac94224ea18a4119/python/src/aac/spec/spec.yaml#L119-L149
• [ ] Create a schema definition of ConstraintReference. Similar to current ValidationReference. https://github.com/DevOps-MBSE/AaC/blob/0b2eb2b419c06f929f072a24ac94224ea18a4119/python/src/aac/spec/spec.yaml#L150-L159
• [ ] Create a schema definition of ConstraintInput. Similar to current ValidatorInput. https://github.com/DevOps-MBSE/AaC/blob/0b2eb2b419c06f929f072a24ac94224ea18a4119/python/src/aac/spec/spec.yaml#L160-L167
• [ ] Create a schema definition of ConstraintOutput. Similar to current ValidatorOutput. https://github.com/DevOps-MBSE/AaC/blob/0b2eb2b419c06f929f072a24ac94224ea18a4119/python/src/aac/spec/spec.yaml#L168-L175
