Perhaps the testutils package in the past had an `init()` function to set up
specific things, but it no longer has. so these imports were doing nothing.

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.

drvRegistry isnt aware if a plugin is v1 or v2. Plugin-v2 provides a way
for user to disable and remove plugins. But unfortunately, there isnt
any api to advertise the removal to drvRegistry. Hence there is no way
to handle "docker plugin rm" of installed plugin. In order to support
the case of "docker plugin install x" followed by "docker plugin rm x"
followed by reinstalling of plugin x "docker plugin install x",
drvRegistry must allow overriding any existing plugin with the same
name. The protection in plugin infra will prevent willful override of
existing plugin.

As part of daemon init, network and ipam drivers are passed a
pluginstore object that implements the plugin/getter interface. Use this
interface methods in libnetwork to interact with network plugins. This
interface provides the new and improved pluginv2 functionality and falls
back to pluginv1 (legacy) if necessary.

With the introduction of a driver generic gossip in libnetwork it is not
necessary for drivers to run their own gossip protocol (like what
overlay driver is doing currently) but instead rely on the gossip
instance run centrally in libnetwork. In order to achieve this, certain
enhancements to driver api are needed. This api aims to provide these
enhancements.
The new api provides a way for drivers to register interest on table
names of their choice by returning a list of table names of interest as
a response to CreateNetwork. By doing that they will get notified if a
CRUD operation happened on the tables of their interest, via the newly
added EventNotify call.
Drivers themselves can add entries to any table during a Join call by
invoking AddTableEntry method any number of times during the Join
call. These entries lifetime is the same as the endpoint itself. As soon
as the container leaves the endpoint, those entries added by driver
during that endpoint's Join call will be automatically removed by
libnetwork. This action may trigger notification of such deletion to all
driver instances in the cluster who have registered interest in that
table's notification.

Because overlay is a builtin driver and global allocation of overlay
resources is probably going to happen in a different node (a single
node) and the actual plumbing of the network is probably going to happen
in all nodes, it makes sense to split the functionality of allocation
into two different packages. The central component(this package) only
implements the NetworkAllocate/Free apis while the distributed
component(the existing overlay driver) implements the rest of the driver
api. This way we can reduce the memory footprint overall.

Currently driver management logic is tightly coupled with
libnetwork package and that makes it very difficult to
modularize it and use it separately. This PR modularizes
the driver management logic by creating a driver registry
package.
