Missing `if-match` header in the CSDL metadata

[peombwa]

The CSDL is missing if-match header that's required when updating certain resources. The header should ideally be annotated by the API owners in their CSDL if it is required. The absence of these headers results in errors for customers consuming SDKs built on top of the CSDL.

The following resources are currently missing an If-Match header in the service description:

• delegatedAdminRelationship
• delegatedAdminAccessAssignment

Annotation needed to be updated for the two entities:

 <Annotation Term="Org.OData.Capabilities.V1.UpdateRestrictions">
  <Record>
    <PropertyValue Property="CustomHeaders">
      <Collection>
        <Record>
          <PropertyValue Property="Name" String="If-Match" />
          <PropertyValue Property="Description" String="ETag value." />
          <PropertyValue Property="Required" Bool="true" />
        </Record>
      </Collection>
    </PropertyValue>
  </Record>
</Annotation>
