Support for changing the default compression level when enabling server response compression

[juliojgd]

Motivation

In the server compression related documentation the only configurable parameters are enabled (boolean) and minimum size for a payload to be compressed (int).

There is no method in Reactor Netty HttpServer that allows to set the compression level (int) that is effectively available in Netty's HttpContentCompressor class but it's not available in the default SimpleCompressionHandler

It cannot be set in the Reactor Netty HttpServerResponse either.

Desired solution

To add a configurable property (maybe named "compression-level" or "gzip-compression-level") to allow changing the default compression level (6 - gzip) to any other compression level that the developer needs to set.

@juliojgd Are you interested in providing a PR? Which Reactor Netty version should enable this feature (1.1.x or 1.2.x)?

[juliojgd]

@violetagg we are using Spring Boot 3.2.x so I guess we'd need 1.1.x. I'll try to provide a PR.

The source branch to checkout for the changes would be https://github.com/reactor/reactor-netty/tree/1.1.x , right?

Thanks in advance
