When the shim returns a plain error when a process does not exist,
the server is unable to recognise its GRPC status code and assumes
UnknownError. This is awkward for containerd client users as they are
unable to recognise the actual reason for the error.
When the shim returns a NotFound GRPC error, it is properly translated
by the server and clients receive a proper NotFound error instead of
Unknown
Please note that we (CF Garden) would like to have the eventual fix backported to 1.4 as well.

containerd is responsible for creating the log but there is no code to ensure
that the log dir exists. While kubelet should have created this there can be
times where this is not the case and this can cause stuck tasks.

oom_score_adj must be in the range -1000 to 1000. In AdjustOOMScore if containerd's score is already at the maximum value we should set that value for the shim instead of trying to set 1001 which is invalid.

WithAdditionalContainerLabels() preserves the existing entries in c.Labels.
OTOH, WithContainerLabels() clears them.

The additional []containerd.RemoteOpt is not used by ctr currently,
but planned to be used by nerdctl and also probably by stargz's ctr-remote.

zstd is a compression algorithm that has a very fast decoder, while
providing also good compression ratios. The fast decoder makes it
suitable for container images, as decompressing the tarballs is a very
expensive operation.
https://github.com/opencontainers/image-spec/pull/788 added support
for zstd to the OCI image specs.
