### What changes were proposed in this pull request?
This PR enhances the Ratis peer add operation to support clientAddress and adminAddress parameters with RESTful api, allowing these critical RPC endpoints to be properly configured when adding new peers to the Celeborn master cluster.
### Why are the changes needed?
Currently, when expanding the Celeborn master cluster using the ratis peer add operation, newly added peers lack clientAddress and adminAddress settings. If a newly added peer becomes the Leader, all Followers will return empty addresses to clients, causing them to attempt connections to an incorrect Leader address (127.0.0.1:0). This change ensures proper client request routing in expanded clusters.
### Does this PR introduce _any_ user-facing change?
Yes, this PR extends the API for adding Ratis peers by adding support for clientAddress and adminAddress parameters. Users will now be able to specify these addresses when adding new peers to the cluster.
### How was this patch tested?
Manual testing of cluster expansion scenarios to ensure clients can correctly connect to the Leader regardless of which peer holds leadership
