Add and initialize cluster id in the TSO service (#6138)
ref #5836 Add and initialize cluster id in the TSO service. PD/API service discovery gets cluster id from the API service. It then passes the cluster id to the TSO service because both share the same cluster id. Signed-off-by: Bin Shi <[email protected]>
