[Server] refactor: exporter interface

[jiekun]

This PR is for:

#3926

Trying to provide export interface:

type Exporter interface {
	// Start starts an exporter worker
	Start()

	// Put sends data to the exporter worker. Worker could decide what to do next. e.g.:
	// - send it out synchronously.
	// - store it in a queue and handle it later.
	Put(items ...interface{})

	// IsExportData tell the decoder if data need to be sended to specific exporter.
	IsExportData(items interface{}) bool
}

And a factory init method for all exporters:

func NewExporters(exportersCfg []ExporterCfg, baseCfg *config.Config) []Exporter

This is a breaking change against previous exporter config. We need an item in CHANGELOG to notify user.
I'm verifying the change and test it on my Kubernetes. This PR is WIP for now.

I'm merging the main branch into feature branch, again. please take a look and drop your comment if possible.
We don't have to waste time running CICD workflow with limited runner resources for those redundant test and check.

@lzf575 Have time to review it as soon as possible

有些配置是公共的， universalTagsManager 也是公共的， 后续需单独提取出来。
