"name" field should be basename, which doesn't include link information

When we link some containers with another, sometimes this plugin generate fields which are dfficult to deal with (like containerA/containerB). As shown in the following sample, this happens for a reason of using Docker::Container.info method. With using Docker::Container.json, we can get basename of containers.

Docker::Container.all.map{|container| container.info['Names'] }
=> [["/fluentd"],  ["/fluentd/norikra", "/norikra"]]

Docker::Container.all.map{|container| container.json['Name'] }
=> ["/fluentd", "/norikra"]

I agree though this could break some workflows. Maybe there needs to be a name tag and a base name tag.
