Lps 43608 Add support to config address used by cluster manually

Hi Shuyang,

It does not make scene to use local address and server port to load lucene from cluster, for "When using apache to do load balancing, if the first request is redirected by apache, it is unable to get correct http port cause it is not using http connector. "

So we can not just back port part of the changes, so I put all together.

Tina.
