When an endpoint is joined by a container it may
optionally pass a priority to resolve resource
conflicts inside the sandbox when more than one
endpoint provides the same kind of resource. If the
the priority is the same for two endpoints with
conflicting resources then the endpoint network names
are used to resolve the conflict.

- The libnetwork test code had some issues in not properly
passing the network options. Fixed it.
- Made controller a global value so that every test uses the
same controller instance.
- Cleaned up endpoint and network objects after every test.
- Extended the endpoint join test case to test the same container
join two different networks using two different endpoints.

This PR attempts to work around bugs present in kernel
version 3.18-4.0.1 relating to namespace creation
and destruction. This fix attempts to avoid certain
systemmcalls to not get in the kkernel bug path as well
as lazily garbage collecting the name paths when they are removed.

Do not have log output in packages that applications consume because the
output can mess with logs, stdout/stderr of applications and such and
there is nothing that the consumer can do about it other than change the
package that they are using.

Sir Codus Cleanupus vs. system.go
"This code doth offend me so" uttered Sir Codus Cleanupus
"and thus it must be cleft swiftly in twain". With one hefty
stroke of his broadsword he carved the old, unfunctioning
code in half and thus it ceased to be.

Now that Endpoint interface has the Info method there is no
need to return container data as a return value in the Join
method. Removed the return value and fixed all the callers.
