---------------------------------------------

Devlist thread: 
http://apache-ignite-developers.2346864.n4.nabble.com/S3-discovery-and-docker-bridge-networks-tt39728.html.

Also, this seems to be relatively simple, so marking as 'newbie'. Might turn 
out to be harder though.

> Problem:  In some deployments, there are multiple IP addresses,  and  S3 
> discovery tries them in some random order, and times out on the ones that 
> don't work, slowing down discovery unnecessarily.   In many such cases, the 
> set of unusable address is known by humans, but is not discoverable at 
> runtime.   For example, some IP addresses may be blocked by firewalls.   On 
> ECS, the docker bridge network IPs are visible, but are unusable across nodes.
> The node pushing IPs to S3 does not have the enough info to decide which of 
> its address is valid.
