Fix missing change name ovn central

function start-ovn-ic must check if OVN_DB_CLUSTER is being used
to set CENTRAL_IC_ID name.
Running the following command, you will see the problem:
OS_BASE=ubuntu OS_IMAGE=docker.io/library/ubuntu:jammy ENABLE_SSL=no CENTRAL_COUNT=1 GW_COUNT=4 CHASSIS_COUNT=4 ./ovn_cluster.sh start

It creates ovn central with name ovn-central-az1, and function try to use ovn-central-az1-1
