Graal support in the backend-platform

[viktorklang]

It would be extremely interesting to be able to make the sidecar application a Graal Native Image.

https://github.com/oracle/graal/blob/master/substratevm/CONFIGURE.md

One possible solution is to have the AKKA backend Reference Implementation launched in a Graal Docker Image with the Assisted Configuration agentlib enabled, then running a simulation to exercise all the code paths needed to generate a configuration, which can then be fed into the native image builder to generate a native image of the RI.

This is also worth keeping an eye on, as it is currently cumbersome to deal with sunec.dylib: oracle/graal#1336
