nacos

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.

This version contains several optimizations and bug fixes, and also some important features.

Extended health checker are now supported #359. Thanks to the contribution of @XCXCXCXCX, you can follow the README to build your own health checkers.

We also introduce a new interface NamingMaintainService in #747, which contains methods to update instances and edit services. Thanks to @chuntaojun.

Hostname can now be registered in Nacos, the related issue is #963. Thanks to @Albert-Hugo.

The complete list of issues is:

This is the GA version of Nacos, which is ready to be put into large scale production environment.

We introduce several significant new features and optimizations in this version, most of which have been released in our previous RC versions. It took us about one month to stabilize and optimize this GA version, in which we fixed several bugs and accommodated some of our default behaviors. We also conducted a stress test to measure the performance and capacity of Nacos.
