Draft ICE

[xinze-zheng]

Description

This is a draft for TURN STUN sidecar for ION. I'm hoping to have some feedbacks before proceeding.

• Implements STUN-only (not TCP support) and STUN-TURN service
• ice/config.go implements logic to parse an endoint to one of (stun|turn|stun-turn). This allows sidecar to run corresponding services.
• Lots of unit tests and integration tests with clients.

TODO

• TURN-only service using allocaiton callback.
• Metrics
• Quota
• Dockerfile
• More integration test

Reference issue

Fixes #20 #21

Overall great draft that we can work on. I would like to see / add:

1. RFC 7064/7065 addresses for turn / stun settings.
2. /healthz + metrics.
3. clear IPv6 support.
4. more coverage.
   But this is a good base that we can work on, after you merge our PR i'm going to add few PRs to add some features on top of it.
   Really great work, thank you..

Nit: I would like to be able to configure TLS versions.

We should be able to configure the relay address.

Configs now calls a validation check for valid fields, endpoint, non empty fields, etc. during load.
