Breaking changes

• We moved our repository module under api module. There will be no 0.5.0 version for ai.djl.repository, use ai.djl.api instead.
• Please refer to DJL Java Doc for some minor API changes.

Know issues:

• Issue when using multiple Engines at the same time: #57
• Issue using DJL with Quarkus: #67
• We saw random crash on mac for transfer Learning on CIFAR-10 Dataset example on Jupyter Notebook. Command line all works.
