This change simplifies the CRI plugin dependencies by not requiring the
CRI image plugin to depend on any other CRI components. Since other CRI
plugins depend on the image plugin, this allows prevents a dependency
cycle for CRI configurations on a base plugin.

To break the cyclic dependency of cri plugin and podsandbox plugin,
we define a new plugin type of SandboxesServicePlugin and when cri init
it's own client, it will add the all the controllers by get them from
the SandboxesServicePlugin.
when podsandbox controller init it's client, it will not Require the
SandboxesServicePlugin.

When call sandbox controller to create sandbox, we change the param from
sandbox id to total sandbox object to git all information to controller,
so that sandbox controller do not rely on the sandbox store anymore,
this is more decouple for the sandbox controller plugin inside
containerd, and it is neccesary for remote sandbox controller plugins as
it is not able to get sandbox from the sandbox store anymore.

make containerd extensible to support more sandbox controllers
registered into containerd by config.
we change the default sandbox controller plugin's name from "local" to "shim".
to make sure we can get the controller by the plugin name it registered into
containerd.
