A fifo on unix or named pipe on Windows will be provided to the shim. It can be located inside the `cwd` of the shim named "log". The shims can use the existing `github.com/containerd/containerd/log` package to log debug messages. Messages will automatically be output in the containerd's daemon logs with the correct fiels and runtime set. Signed-off-by: Michael Crosby <crosbymichael@gmail.com>
