Wire in enableReplication into operator api

[michaely520]

What changed?

Wiring in #8658 but for operator api

Why?

Compatibility with CLI

How did you test it?

• built
• run locally and tested manually
• covered by existing tests
• added new unit test(s)
• added new functional test(s)

in our functional test I commented out

	// Enable replication active -> standby
	_, err = activeCluster.AdminClient().AddOrUpdateRemoteCluster(
		ctx,
		&adminservice.AddOrUpdateRemoteClusterRequest{
			FrontendAddress:               standbyCluster.Host().RemoteFrontendGRPCAddress(),
			FrontendHttpAddress:           standbyCluster.Host().FrontendHTTPAddress(),
			EnableRemoteClusterConnection: true,
			EnableReplication:             true, // NOW enable replication
		})
	s.Require().NoError(err)

	// Enable replication standby -> active
	_, err = standbyCluster.AdminClient().AddOrUpdateRemoteCluster(
		ctx,
		&adminservice.AddOrUpdateRemoteClusterRequest{
			FrontendAddress:               activeCluster.Host().RemoteFrontendGRPCAddress(),
			FrontendHttpAddress:           activeCluster.Host().FrontendHTTPAddress(),
			EnableRemoteClusterConnection: true,
			EnableReplication:             true, // NOW enable replication
		})
	s.Require().NoError(err)

and used a locally built cli temporalio/cli#881 to enable, test passed
