"docker.sock" is used to access Docker API which is required to:
1. subscribe to Docker events to configure-arp,
2. query Docker network info to detect whether multicast should be
enabled.
3. get list of Swarm peers before starting the plugin.
(1) is currently not implemented.
(2) is replaced by WEAVE_MULTICAST env var which
can enable multicast for all Weave networks created by
the plugin (not ideal, but better than nothing).
(3) is fixed by not removing "restart.sentinel".

Why:
* In some environments Nodes have an ExternalIP but no InternalIP
This change addresses the need by:
* Falling back to ExternalIP addresses if there isn't an InternalIP for a node

This logic was added for backward compatibility and to warn users about changes made ~2 years ago.
Given we are planning a 2.0 release for Weave Net, such logic is now irrelevant and can be removed.
