Impactful Client Updates

This release has changes which may affect projects which import containerd.

Switch to Go modules

containerd and all containerd sub-repositories are now using Go modules. This
should help make importing easier for handling transitive dependencies. As of
this release, containerd still does not guarantee client library compatibility
for 1.x versions, although best effort is made to minimize impact from changes
to exported Go packages.

CRI plugin moved to main repository

With the CRI plugin moving into the main repository, imports under github.com/containerd/cri/
can now be found github.com/containerd/containerd/pkg/cri/.
There are no changes required for end users of CRI.

Library changes

oci

The WithAllCapabilities has been removed and replaced with WithAllCurrentCapabilities
and WithAllKnownCapabilities. WithAllKnownCapabilities has similar
functionality to the previous WithAllCapabilities with added support for newer
capabilities. WithAllCurrentCapabilities can be used to give privileged
containers the same set of permissions as the calling process, preventing errors
when privileged containers attempt to get more permissions than given to the
caller.
