Provide a way to configure each plugin.

[minwoox]

Motivation: Configuring user-defined plugins is currently difficult because there is no way to configure their properties via dogma.json.

Modifications:

• Added PluginConfig interface that represents a configuration of a plugin.
• Added pluginConfigs to CentralDogmaConfig that accepts a list of PluginConfig.
  • Users can now configure each plugin using PluginConfig.
• Moved mirroring plugin properties from CentralDogmaConfig to MirroringServicePluginConfig.
  • Compatibility was not maintained as few users are running the Central Dogma server, and they can be guided directly. Let me know if a different approach is preferred.

Result:

• Users can now specify plugin configurations in the plugins property.

  {
  "dataDir": "./data",
  ...
  "pluginConfigs": [
    {
      "type": "com.example.MyPlugin",
      "enabled": true, // enabled by default
      "myPluginTimeout": 10
    },
    // Other plugins
  ]
  }

• (Breaking changes) mirroringEnabled, numMirroringThreads, maxNumFilesPerMirror, and maxNumBytesPerMirror have been removed from CentralDogmaBuilder and CentralDogmaConfig.
  • These properties should now be specified in the plugins property:

    {
    "dataDir": "./data",
    ...
    "pluginConfigs": [
    {
      "type": "com.linecorp.centraldogma.server.mirror.MirroringServicePluginConfig",
      "enabled": true,
      "numMirroringThreads": 16,
      "maxNumFilesPerMirror": 8192
    }  
    ]
    }

I haven't fixed the documentation yet. I will update it once the changes are accepted.

Thanks a lot for reviewing. 😉
