Enable OVNDBCluster metrics collection

Add Prometheus metrics support to OVNDBCluster by configuring the
openstack-network-exporter sidecar container. This enables monitoring
of OVSDB server metrics through the same pattern used for OVNNorthd.

Changes include:
- Add ExporterImage assignment for OVNDBCluster reconciliation
- Update container image status tracking for OpenstackNetworkExporter
