This version mainly refactors the distro protocol of the naming module and sinks to the nacos-core module. At the same time, jraft is used to replace the old self-implemented raft protocol to improve the performance and accuracy of raft semantics. Secondly, this version completely unifies the http clients used by nacos, optimizes the usage of some http clients, and reduces connection cost, especially the number of CLOSE_WAIT connections. Finally, fixed some old version bugs and optimized console usage, and added a BETA interface to modify service metadata separately.
