Bug 32495: Mis-matched required fields in UI and api

The "description" field is marked as required in the UI when creating a new Agreement. This flag has been removed to match the API where it is not a required field. Is Perpetual has not been marked as required as it is a checkbox with a default selection so will always provide a value.

Test plan:
1) In the ERM module, add a new agreement and observe that the Description field is required
2) Apply patch
3) Repeat step 1 but this time the Required flag will not be visible.
