Before this patch libcontainer badly errored out with `invalid
argument` or `numerical result out of range` while trying to write
to cpuset.cpus or cpuset.mems with an invalid value provided.
This patch adds validation to --cpuset-cpus and --cpuset-mems flag along with
validation based on system's available cpus/mems before starting a container.

Add a daemon flag to control this behaviour. Add a warning message when pulling
an image from a v1 registry. The default order of pull is slightly altered
with this changset.
Previously it was:
https v2, https v1, http v2, http v1
now it is:
https v2, http v2, https v1, http v1
Prevent login to v1 registries by explicitly setting the version before ping to
prevent fallback to v1.
Add unit tests for v2 only mode. Create a mock server that can register
handlers for various endpoints. Assert no v1 endpoints are hit with legacy
registries disabled for the following commands: pull, push, build, run and
login. Assert the opposite when legacy registries are not disabled.

Use `pkg/discovery` to provide nodes discovery between daemon instances.
The functionality is driven by two different command-line flags: the
experimental `--cluster-store` (previously `--kv-store`) and
`--cluster-advertise`. It can be used in two ways by interested
components:
1. Externally by calling the `/info` API and examining the cluster store
field. The `pkg/discovery` package can then be used to hit the same
endpoint and watch for appearing or disappearing nodes. That is the
method that will for example be used by Swarm.
2. Internally by using the `Daemon.discoveryWatcher` instance. That is
the method that will for example be used by libnetwork.

Absorb Swarm's discovery package in order to provide a common node
discovery mechanism to be used by both Swarm and networking code.

* Thanks to the Default gateway service in libnetwork, we dont have to add
containers explicitly to secondary public network. This is handled
automatically regardless of the primary network driver.
* Fixed the URL convention for kv-store to be aligned with the upcoming
changes to discovery URL
* Also, in order to bring consistency between external and internal network
drivers, we moved the driver configs via controller Init.
