New Features

• Added multi-gpu implementation for PPO. You can turn this on by using --multi-gpu option in mlagents-learn. In our own experiments we've observed a 38% boost on the update speed of Resnet using the Obstacle Tower Environment. (#2288)

Fixes and Improvements

• Improved the training performance by 20-30% when curiosity is used. We achieved this by updating the reward signal in parallel with the policy. (#2362)
• Changed the Crawler example environment observation space to include relative observations. Increases performance in CrawlerDynamic scene. (18f661)
• Fixed a bug with online Behavior Cloning. (#2384)
