TE-4.1: Base Leader Election

Validate Election ID is accepted from a gRIBI client.

Connect DUT port-1 to ATE port-1, DUT port-2 to ATE port-2, DUT port-3 to ATE port-3. Assign IPv4 addresses to all ports.
Establish two gRIBI clients to the DUT (referred to as gRIBI-A and gRIBI-B).
Connect gRIBI-A to DUT specifying PRESERVE persistent mode, SINGLE_PRIMARY client redundancy in the SessionParameters request. Ensure that no error is reported from the gRIBI server.
Connect gRIBI-B to DUT specifying PRESERVE persistent mode, SINGLE_PRIMARY client redundancy and make it become leader.
Add an IPv4Entry for 198.51.100.0/24 pointing to ATE port-3 via gRIBI-B, ensure that the entry is active through AFT telemetry and traffic.
Add an IPv4Entry for 198.51.100.0/24 pointing to ATE port-2 via gRIBI-A, ensure that the entry is ignored by the DUT.
Make gRIBI-A become leader, followed by a ModifyRequest updating 198.51.100.0/24 pointing to ATE port-2, ensure that routing is updated to receive packets for 198.51.100.0/24 at ATE port-2.
