1.0.0-M2

Highlights

As part of the same work flatbuffers has been upgraded to 1.12.1. This affects the samediff file format and the user interfaces. Flatbuffers as a file format is forwards and backwards compatible but if you have any issues please do let us know. The relevant files have been updated using the flatc compiler.
Removed rl4j: in continuing to cut unmaintained modules, the 1.0 will focus the framework on a few key use cases. This invites other folks to build external modules for a tightly maintained core that focuses on deployment, framework interop and training models in java.
Added new model zoo module called omnihub for dl4j and new samediff models. These can be found here: https://github.com/KonduitAI/omnihub-zoo See more in the new omnihub section.
Migrated the snapshots to sonatype's new repository https://s01.oss.sonatype.org. More context can be found here: https://twitter.com/Brian_Fox/status/1357414532512104448 https://github.com/eclipse/deeplearning4j/pull/9618
Consolidated tests to platform-tests to allow for easy testing of behavior against different backends.

Omnihub

Launches new Omnihub module. Allows access to models from: https://github.com/KonduitAI/omnihub-zoo
A pretrained omnihub module will provide access to pretrained samediff and dl4j modules. This will also supplant the old dl4j zoo.
