Go deprecation comments must be formatted to have an empty comment line before
them. Fix the formatting to make sure linters and editors detect that these
are deprecated.

In the refactor from 926b9c72f61b5be6bf8d952512f1d0932fbaf898, the error
handling was substantially reworked, and changed the types of errors
returned.
Notably, in the case of a network error, instead of propogating the
error through to return from pushWriter.Write (as previously), it would
be propagated through to pushWriter.Commit - however, this is too late,
since we've already closed the io.Pipe by the time we would have reached
this function. Therefore, we get the generic error message "io:
read/write on closed pipe" for *every network error*.
This patch corrects this behavior to ensure that the correct error
object is always returned as early as possible, by checking the error
result after writing and detecting a closed pipe.
Additionally, we do some additional hardening - specifically we prevent
falling through when resetting the content or detecting errors, and
update the tests to explicitly check for the ErrReset message.

Add spans around image unpack operations
Use image.ref to denote image name and image.id for the image config digest
Add top-level spand and record errors in the CRI instrumentation service
when a put request is retried due to the response from registry,
the body of the request should be seekable. A dynamic pipe is added
to the body so that the content of the body can be read again.
Currently a maximum of 5 resets are allowed, above which will fail the
request. A new error ErrReset is introduced which informs that a
reset has occured and request needs to be retried.
also added tests for Copy() and push() to test the new functionality

`ioutil` has been deprecated by golang. All the code in `ioutil` just
forwards functionality to code in either the `io` or `os` packages.

Schema 1 has been substantially deprecated since circa. 2017 in favor of Schema 2 introduced in Docker 1.10 (Feb 2016)
and its successor OCI Image Spec v1, but we have not officially deprecated Schema 1.
One of the reasons was that Quay did not support Schema 2 so far, but it is reported that Quay has been
supporting Schema 2 since Feb 2020 (moby/buildkit issue 409).
This PR deprecates pulling Schema 1 images but the feature will not be removed before containerd 2.0.
Pushing Schema 1 images was never implemented in containerd (and its consumers such as BuildKit).
Docker/Moby already disabled pushing Schema 1 images in Docker 20.10 (moby/moby PR 41295),
but Docker/Moby has not yet disabled pulling Schema 1 as containerd has not yet deprecated Schema 1.
(See the comments in moby/moby PR 42300.)
Docker/Moby is expected to disable pulling Schema 1 images in future after this deprecation.
