migrate to github.com/containerd/log v0.1.0
The github.com/containerd/containerd/log package was moved to a separate
module, which will also be used by upcoming (patch) releases of containerd.

This patch moves our own uses of the package to use the new module.

libnetwork: arrangeUserFilterRule: don't return early
commit ffd75c2e0c updated this function to
set up the DOCKER-USER chain for both iptables and ip6tables, however the
function would return early if a failure happened (instead of continuing
with the next iptables version).

This patch extracts setting up the chain to a separate function, and updates
arrangeUserFilterRule to log the failure as a warning, but continue with
the next iptables version.

libnetwork: Controller: combine iptablesEnabled and ip6tablesEnabled
These functions were mostly identical, except for iptables being enabled
by default (unless explicitly disabled by config).

Rewrite the function to a enabledIptablesVersions, which returns the list
of iptables-versions that are enabled for the controller. This prevents
having to acquire a lock twice, and simplifies arrangeUserFilterRule, which
can now just iterate over the enabled versions.

Also moving this function to a linux-only file, as other platforms don't have
the iptables types defined.

This unifies our logging and allows us to propagate logging and trace
contexts together.

Revert "libnetwork: Support IPv6 in arrangeUserFilterRule()"
This reverts commit 2d397beb00.

moby#44706 and moby#44805 were both merged, and both refactored the same
file. The combination broke the build, and was not detected in CI as
only the combination of the two, applied to the same parent commit,
caused the failure.

moby#44706 should be carried forward, based on the current master, in
order to resolve this conflict.

a0a473125b Fix libnetwork imports
After moving libnetwork to this repo, we need to update all the import
paths for libnetwork to point to docker/docker/libnetwork instead of
docker/libnetwork.
This change implements that.

fcb70a0e86 DOCKER-USER chain not created when IPTableEnable=false.
This fix addresses https://docker.atlassian.net/browse/ENGCORE-1115
Expected behaviors upon docker engine restarts:
1. IPTableEnable=true, DOCKER-USER chain present
   -- no change to DOCKER-USER chain
2. IPTableEnable=true, DOCKER-USER chain not present
   -- DOCKER-USER chain created and inserted top of FORWARD
      chain.
3. IPTableEnable=false, DOCKER-USER chain present
   -- no change to DOCKER-USER chain
      the rational is that DOCKER-USER is populated
      and may be used by end-user for purpose other than
      filtering docker container traffic. Thus even if
      IPTableEnable=false, docker engine does not touch
      pre-existing DOCKER-USER chain.
4. IPTableEnable=false, DOCKER-USER chain not present
   -- DOCKER-USER chain is not created.

c348cebe99 Add a filter chain to allow persistent rules
Allow users to configure firewall policies in a way that persists
docker operations/restarts. Docker will not delete or modify any
pre-existing rules from the DOCKER-USER filter chain. This allows
the user to create in advance any rules required to further
restrict access from/to the containers.

Fixes docker/docker#29184
Fixes docker/docker#23987
