By default, the cgroup setting in libcontainer's configs.Cgroup for
memory swappiness will default to 0, which is a valid choice for memory
swappiness, but that means by default every container's memory
swappiness will be set to zero instead of the default 60, which is
probably not what users are expecting.
When the swappiness UI PR comes into Docker, there will be docker run
controls to set this per container, but for now we want to make sure
*not* to change the default, as well as work around an older kernel
issue that refuses to allow it to be set when cgroup hiearchies are in
use.

As part of this some generic packages like iptables, etchosts and resolvconf
have also been moved to libnetwork. Even though they can still be
consumed in a generic fashion they will reside and be maintained
from within the libnetwork project.

- Updated Dockerfile to satisfy libnetwork GOPATH requirements.
- Reworked daemon to allocate network resources using libnetwork.
- Reworked remove link code to also update network resources in libnetwork.
- Adjusted the exec driver command population to reflect libnetwork design.
- Adjusted the exec driver create command steps.
- Updated a few test cases to reflect the change in design.
- Removed the dns setup code from docker as resolv.conf is entirely managed
in libnetwork.
- Integrated with lxc exec driver.

`lxc-stop` does not support sending arbitrary signals.
By default, `lxc-stop -n <id>` would send `SIGPWR`.
The lxc driver was always sending `lxc-stop -n <id> -k`, which always
sends `SIGKILL`. In this case `lxc-start` returns an exit code of `0`,
regardless of what the container actually exited with.
Because of this we must send signals directly to the process when we
can.
Also need to set quiet mode on `lxc-start` otherwise it reports an error
on `stderr` when the container exits cleanly (ie, we didn't SIGKILL it),
this error is picked up in the container logs... and isn't really an
error.
Also cleaned up some potential races for waitblocked test.

The `--userland-proxy` daemon flag makes it possible to rely on hairpin
NAT and additional iptables routes instead of userland proxy for port
publishing and inter-container communication.
Usage of the userland proxy remains the default as hairpin NAT is
unsupported by older kernels.

To help avoid version mismatches between libcontainer and Docker, this updates libcontainer to be the source of truth for which version of logrus the project is using. This should help avoid potential incompatibilities in the future, too. 👍
