Add docker-friendly remote service discovery providers

tcalmant commented 7 years ago

Multicast is not available on Docker networks, which means that most of built-in discovery services can't work on that kind of architecture.

The following providers could be interesting to handle this situation:

Broadcast discovery (this might work on Docker)
Key-Value servers (ZooKeeper, Redis, ...) discoveries
- based on hostnames
- based on all available IPs, with a Framework UUID check on each IPs
File-based discovery (requires static host names or IPs and a static binding port)
[x] Redis discovery
[x] Zookeeper discovery
