Vendor docker/docker, fsouza and more #2

Signed-off-by: TomSweeneyRedHat <tsweeney@redhat.com>

Vendors in fsouza/docker-client, docker/docker and
a few more related. Of particular note, changes to the TweakCapabilities()
function from docker/docker along with the parse.IDMappingOptions() function
from Buildah. Please pay particular attention to the related changes in
the call from libpod to those functions during the review.

Passes baseline tests.

+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing

+# libnetwork - networking for containers
+
+[![Circle CI](https://circleci.com/gh/docker/libnetwork/tree/master.svg?style=svg)](https://circleci.com/gh/docker/libnetwork/tree/master) [![Coverage Status](https://coveralls.io/repos/docker/libnetwork/badge.svg)](https://coveralls.io/r/docker/libnetwork) [![GoDoc](https://godoc.org/github.com/docker/libnetwork?status.svg)](https://godoc.org/github.com/docker/libnetwork) [![Go Report Card](https://goreportcard.com/badge/github.com/docker/libnetwork)](https://goreportcard.com/report/github.com/docker/libnetwork)
+
+Libnetwork provides a native Go implementation for connecting containers
+
+The goal of libnetwork is to deliver a robust Container Network Model that provides a consistent programming interface and the required network abstractions for applications.
+
+#### Design
+Please refer to the [design](docs/design.md) for more information.
+
+#### Using libnetwork
+
+There are many networking solutions available to suit a broad range of use-cases. libnetwork uses a driver / plugin model to support all of these solutions while abstracting the complexity of the driver implementations by exposing a simple and consistent Network Model to users.
+
+
+```go
+import (
+	"fmt"
+	"log"
+
+	"github.com/docker/docker/pkg/reexec"
+	"github.com/docker/libnetwork"
+	"github.com/docker/libnetwork/config"
+	"github.com/docker/libnetwork/netlabel"
+	"github.com/docker/libnetwork/options"
+)
+
+func main() {
+	if reexec.Init() {
+		return
+	}
+
+	// Select and configure the network driver
+	networkType := "bridge"
+
+	// Create a new controller instance

+	network, err := controller.NewNetwork(networkType, "network1", "")
+	if err != nil {
+		log.Fatalf("controller.NewNetwork: %s", err)
+	}
+
+	// For each new container: allocate IP and interfaces. The returned network
+	// settings will be used for container infos (inspect and such), as well as
+	// iptables rules for port publishing. This info is contained or accessible
+	// from the returned endpoint.
+	ep, err := network.CreateEndpoint("Endpoint1")
+	if err != nil {
+		log.Fatalf("network.CreateEndpoint: %s", err)
+	}
+
+	// Create the sandbox for the container.
+	// NewSandbox accepts Variadic optional arguments which libnetwork can use.
+	sbx, err := controller.NewSandbox("container1",
+		libnetwork.OptionHostname("test"),
+		libnetwork.OptionDomainname("docker.io"))
+	if err != nil {
+		log.Fatalf("controller.NewSandbox: %s", err)
+	}
+
+	// A sandbox can join the endpoint via the join api.
+	err = ep.Join(sbx)
+	if err != nil {
+		log.Fatalf("ep.Join: %s", err)
+	}
+
+	// libnetwork client can check the endpoint's operational data via the Info() API
+	epInfo, err := ep.DriverInfo()
+	if err != nil {
+		log.Fatalf("ep.DriverInfo: %s", err)
+	}
+
+	macAddress, ok := epInfo[netlabel.MacAddress]
+	if !ok {
+		log.Fatalf("failed to get mac address from endpoint info")
+	}
+
+	fmt.Printf("Joined endpoint %s (%s) to sandbox %s (%s)\n", ep.Name(), macAddress, sbx.ContainerID(), sbx.Key())
+}
+```
