Enhancement for constant variables.

[jzdayz]

Issue Description

Type: code review

Describe what happened (or what feature you want)

I noticed that there are some magic variables in applicationUtils and PropertyUtil, can it be written in one place,it's so messy. i think all config magic variables should be one place

Describe what you expected to happen

If it passes, I can do this

How to reproduce it (as minimally and precisely as possible)

Tell us your environment

Anything else we need to know?

so messy

• plan1

public interface Constants {
    interface Raft{

    }

    interface Nacos{
        String FUNCTION_MODE_PROPERTY_NAME = "nacos.functionMode";
    }

    interface Web{
        String ACCEPT_CHARSET = "Accept-Charset";
        String SERVER_PORT = "server.port";
    }
}

• plan2

public class Constants {
    public static class Raft{

    }

    public static class Nacos{
        public static String FUNCTION_MODE_PROPERTY_NAME = "nacos.functionMode";
    }

    public static class Web{
        public static String ACCEPT_CHARSET = "Accept-Charset";
        public static String SERVER_PORT = "server.port";
    }
}

Looks great, but I can't get the difference between the two plan, I think plan two is more used.

If you want to do this, please pay attention to the scope of these constants.

@jzdayz Any progress？

Sorry, in my idea, I want to put all the constants in common module, but I found that there are constant classes in different modules, so I think that if the code is modified, the range of changes will be larger. I think the code in the future It can be unified, but I dare not move the current code

@jzdayz you can split this issue as multiple sub task. each module each task. And refactor for each module.
After all modules has finished, then to think about merge constants and unified them.

[KomachiSion]

For example:

• refactor constants in naming module
• refactor constants in config module
  ....
• merge and unified constants for modules.

OK,i got this , let me think , modify one by one

[KomachiSion]

@jzdayz There is no process for a long time, I unassign this issue for you first. If you want to solve it, please relay again with new process.
