  * add more constructor for PeerId.

  * use brpc naming_service_url init channel API to force resolv dns.
  * modify raft_meta log saved format when PeerId type is HostName.
  * init channels only once and save them for future use
* define a struct named HostNameAddr, as an attribute of PeerId
* wrap a function to build naming_service_url, which is used for brpc channel init
* modify logic about channel init with naming service
* minor fix about hostnameAddr port_ type

It would be really useful for braft to support hostname/dns for PeerId as it will allow it to be used on Kubernetes that dynamically assigns IPs.

looks fine! but it's complex for me, I think you should replace brpc::Init(server_and_port, nullptr) with brpc::Init(service, "rr", nullptr),because the brpc::Init(service, "rr", nullptr) can compatible with brpc::Init(service_and_port, nullptr).
