   ### Motivation
   Pulsar doesn't support deploy on IPv6 network environment.
   This PR just makes an effort to make it.
   The error happens if the client connect to brokers by IPv6 address, like fec0:0:0:ffff::1.
   - Wrong format: fec0:0:0:ffff::1:6650
   - Correct format: [fec0:0:0:ffff::1]:6650
   
   Cause the split regex is ':', brackets are needed and the ip:port can't split by ':' directly.
   
   ### Modifications
   
   validateHostName in ServiceURI
