Kaniko Multi Stage in parallel

[Ahmet Demir]

Hello world,

I try my chance here, we have a build with several build stage (compilation) with a final stage taking all compiled binaries.
It takes several minutes instead of some to build the image.

Looks like this issue could be easily fixed using some goroutine and a simple env/param to define max "worker" to use (like this loop)

There is an open issue with a lot upvote, I could work on it but is it an accepted design or is there a limitation I missed ?
