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.
