Update containerd to v1.2.0
Update containerd to v1.2.0

release notes: https://github.com/containerd/containerd/releases/tag/v1.2.0

- New V2 Runtime with a stable gRPC interface for managing containers through
  external shims.
- Updated CRI Plugin, validated against Kubernetes v1.11 and v1.12, but it is
  also compatible with Kubernetes v1.10.
- Support for Kubernetes Runtime Class, introduced in Kubernetes 1.12
- A new proxy plugin configuration has been added to allow external
  snapshotters be connected to containerd using gRPC.-
- A new Install method on the containerd client allows users to publish host
  level binaries using standard container build tooling and container
  distribution tooling to download containerd related binaries on their systems.
- Add support for cleaning up leases and content ingests to garbage collections.
- Improved multi-arch image support using more precise matching and ranking
- Added a runtime `options` field for shim v2 runtime. Use the `options` field to
  config runtime specific options, e.g. `NoPivotRoot` and `SystemdCgroup` for
  runtime type `io.containerd.runc.v1`.
- Some Minor API additions
  - Add `ListStream` method to containers API. This allows listing a larger
    number of containers without hitting message size limts.
  - Add `Sync` flag to `Delete` in leases API. Setting this option will ensure
    a garbage collection completes before the removal call is returned. This can
    be used to guarantee unreferenced objects are removed from disk after a lease.
