Wei Fu 8a388d6238 leases: support resource management
Add three methods for lease service so that the client can use it to
manage the resource by lease, not just gc.root label. With the following
methods, it is easy for client to maintain their own cache system.

```
 - AddResource(context.Context, Lease, Resource) error
 - RemoveResource(context.Context, Lease, Resource) error
 - ListResources(context.Context, Lease) ([]Resource, error)
```

And the resource is to be

```golang
type Resource {
  ID   string
  Type string
}
```

For the snapshots, the Type field will be formatted by
snapshots/%{type}, like snapshots/overlayfs.

fix: #3295

This directory contains the GRPC API definitions for containerd.

All defined services and messages have been aggregated into *.pb.txt descriptors files in this directory. Definitions present here are considered frozen after the release.

At release time, the current next.pb.txt file will be moved into place to freeze the API changes for the minor version. For example, when 1.0.0 is released, next.pb.txt should be moved to 1.0.txt. Notice that we leave off the patch number, since the API will be completely locked down for a given patch series.

We may find that by default, protobuf descriptors are too noisy to lock down API changes. In that case, we may filter out certain fields in the descriptors, possibly regenerating for old versions.

This process is similar to the process used to ensure backwards compatibility in Go.
