Motivation: GraalVM native images are a new way to deliver java applications. Netty is one of the most popular libraries however there are a few limitations that make it impossible to use with native images out of the box. Adding a few metadata (in specific modules will allow the compilation to success and produce working binaries) Modification: Added properties files in `META-INF` and substitutions classes (under `internal.svm`) will solve the compilation issues. The substitutions classes are not visible and do not have a public constructor so they are not visible to end users. Result: Fixes #8959 This fix is very conservative as it applies the minimum config required to build: * pure netty servers * vert.x applications * grpc applications The build is having trouble due to checkstyle which does not seem to be able to find the copyright notice on property files.
