Pulsar Shell: native image with GraalVM

Search before asking

• I searched in the issues and found nothing similar.

Motivation

Currently pulsar-shell is just a simple java application.
Nowadays GraalVM native image is a great way to package java CLI application into a optimized native binary.
Additionaly it removes the need to having a JDK installed

This might be a starting point here but it's not complete
but currently there are some issues about reflection because Pulsar/Netty uses the reflections a lot.

Moved to the general discussion topic. This is hard to do because GraalVM requires developer to help marking all reflections and resources, as well as some subtle runtime issues.

I ever made a native image Java application at http://github.com/korandoru/hawkeye but it's far more simple than Pulsar Shell case.
