ffdc748861 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.

The proposed changes support multiple IPv6 addresses on a container
interface. If isGW is configured, the bridge will also be configured with
gateway addresses for each IPv6 subnet.

Please note that both the dual-stack functionality and support for multiple
IPv6 container/gateway addresses depends upon containernetworking/cni
PR 451 "ipam/host-local: support multiple IP ranges".
This change could potentially be committed independently from this host-local
plugin change, however the dual-stack and multiple IPv6 address
functionality that is enabled by this change can't be exercised/tested
until the host-local plugin change is committed.

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 the multiple IP range host-local change.

This pull request includes a temporary workaround for Kubernetes
Issue #32291 (Container IPv6 address is marked as duplicate, or dadfailed).
The problem is that kubelet enables hairpin mode on bridge veth
interfaces. Hairpin mode causes the container/pod to see echos of its
IPv6 neighbor solicitation packets, so that it declares duplicate address
detection (DAD) failure. The long-term fix is to use enhanced-DAD
when that feature is readily available in kernels. The short-term fix is
to disable IPv6 DAD in the container. Unfortunately, this has to be done
unconditionally (i.e. without a check for whether hairpin mode is enabled)
because hairpin mode is turned on by kubelet after the CNI bridge plugin
has completed cmdAdd processing. Disabling DAD should be okay if
IPv6 addresses are guaranteed to be unique (which is the case for
host-local IPAM plugin).

2e9e87732f ipam/host-local: support multiple IP ranges 
This change allows the host-local allocator to allocate multiple IPs.
This is intended to enable dual-stack, but is not limited to only two
subnets or separate address families.
