log4j-layout-template-json Add support to Compact Log Event Format

It is highly recommended to discuss feature requests in the mailing lists first.

[A clear and concise description of the feature requested.]

The Problem

Currently log4j2 provides several JSON templates at:

• https://github.com/apache/logging-log4j2/tree/2.x/log4j-layout-template-json/src/main/resources

All of current template will generate log files with long key name, which produces bigger log output.

The Request

We deliver a compact JSON format, like CLEF or similar, to make the log output smaller.

Example: CLEF format could be 47% smaller than the default EcsLayout.json.

Seems interesting,

I would be curious to know, how this is implemented, or looked into. I am getting familiar with the repoo, this looks like an interesting feature for people.

@amosshi, @jaykataria1111, would you mind providing a JSON Template Layout event template for CLEF and publishing it as a part of the CLEF project with a Apache 2 License compatible license, please? If the CLEF community provides such an integration, we would be happy to point to it in the Log4j manual.
