------------------------------------------

Hi [~dongjin]  [~mimaison]

I am interested to this issue, and it seems to be manageable for a newbie like me.  Do you think I could help on this one?
My plan is to follow current structure [~mimaison]  currently working on to add those config. There is a draft PR in a very early stage available here.

> Adds the following options into the Producer, Broker, and Topic configurations:
>  * compression.gzip.buffer: the buffer size that feeds raw input into the Deflator or is fed by the uncompressed output from the Deflator. (available: [512, ), default: 8192(=8kb).)
>  * compression.snappy.block: the block size that snappy uses. (available: [1024, ), default: 32768(=32kb).)
>  * compression.lz4.block: the block size that lz4 uses. (available: [4, 7], (means 64kb, 256kb, 1mb, 4mb respectively), default: 4.)
>  * compression.zstd.window: enables long mode; the log of the window size that zstd uses to memorize the compressing data. (available: [10, 22], default: 0 (disables long mode.))
> All of the above are different but somewhat in common from the point of compression process in that it impacts the memorize size during the process.
