v0.6.5

This version mainly adds:

• Service Factories
• HTTP Routing (based on decorators, HttpGet, HttpPost, ...)
• Redis and ZooKeeper remote service discovery providers (Docker-friendly discovery)
• Added basic support of HTTPS in Remote Services

A big thanks to iPOPO contributors:

• @debovis for fixing a strange behavior when importing a module a bundle depends on
• @Paltoquet for fixing the thread pool
• @ahmadshahwan for preventing imported HTTP servlets to be exposed by the local HTTP server
• @tbr for adding an auto-naming capacity in @Provides decorators and for fixing a bug in normalize_path()
