bridge: Add support for IPv6 to bridge plugin

This change adds support for IPv6 container/pod addresses to the
CNI bridge plugin, both for dual-stack (IPv4 + IPv6) and for IPv6-only
network configurations.

This change could potentially be committed independently from other CNI
IPv6 changes, however the IPv6 functionality that is enabled by this change
can't be exercised/tested without the commits of PR #279 and PR #394.

There are some IPv6 unit test cases that are currently commented out
in the proposed changes because these test cases will fail without the
prior commits of PR #279 and PR #394, however, these test cases have been
tested with patches for PR#279 and PR #394 applied, so they can be
uncommented (enabled) after those dependent PRs are committed.

The proposed changes do not support the case where a dual-stack
network configuration specifies different IPAM plugins for IPv4 vs. IPv6.
Supporting such a configuration would require splitting up the IPv4
IPAM config from the IPv6 IPAM config, and running each IPAM plugin
separately. This is left for future development.

Fixes #415
