The `LastIPInSubnet` function worked only for classful subnet
masks (e.g. /8, /16, /24). For non standard subnet masks this
returned the wrong ip address.
This works now for all subnet mask. A unit test is added to
ensure this.

this enables the ability to connect and disconnect a container from a
given network. it is only for the compatibility layer. some code had to
be refactored to avoid circular imports.
additionally, tests are being deferred temporarily due to some
incompatibility/bug in either docker-py or our stack.

network aliases for container creation

podman can now support adding network aliases when running containers
(--network-alias). It requires an updated dnsname plugin as well as an
updated ocicni to work properly.

enable the ipv6 flag in podman network to be able to create
dual-stack networks for containers.
This is required to be compatible with docker, where --ipv6
really means dual stack.
podman, unlike docker, support IPv6 only containers since

The rootless-cni-infra container always has the dnsname
plugin installed. It makes no sense to check if it is
present on the host.

due to a lack of "locking" on cni operations, we could get ourselves in trouble when doing rapid creation or removal of networks. added a simple file lock to deal with the collision and because it is not considered a performent path, use of the file lock should be ok. if proven otherwise in the future, some generic shared memory lock should be implemented for libpod and also used here.
moved pkog/network to libpod/network because libpod is now being pulled into the package and it has therefore lost its generic nature. this will make it easier to absorb into libpod as we try to make the network closer to core operations.
Fixes: #7807
