Optimized S3 Walk impl by no longer listing files recursively. Overall gives a huge performance increase both in terms of runtime and S3 calls (up to ~500x).
Fixed a bug in WalkFallback where ErrSkipDir for was not handled as documented for non-directory.

Delete was not working when the subpath immediately followed the given path started with an ascii lower than "/" such as dash "-" and underscore "_" and requests no files to be deleted.

According to OCI image spec, the descriptor's digest field is required.
For the normal config/layer blobs, the valivation should check the
presence of the blob when put manifest.

It's possible to configure log fields in the configuration file, and we would
like these fields to be included in all logs. Previously these fields were
included only in logs produced using the main routine's context, meaning that
any logs from a request handler were missing the fields since those use a
context based on the HTTP request's context.
Add a configurable default logger to the `context` package, and set it when
configuring logging at startup time.

Configuration of list of cipher suites allows a user to disable use
of weak ciphers or continue to support them for legacy usage if they
so choose.
List of available cipher suites at:
https://golang.org/pkg/crypto/tls/#pkg-constants
Default cipher suites have been updated to:
- TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
- TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
- TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305
- TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305
- TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
- TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
- TLS_AES_128_GCM_SHA256
- TLS_CHACHA20_POLY1305_SHA256
- TLS_AES_256_GCM_SHA384
MinimumTLS has also been updated to include TLS 1.3 as an option
and now defaults to TLS 1.2 since 1.0 and 1.1 have been deprecated.

Without this, we emit illegal json logs, the user-agent
ends up as:
```
"http.request.useragent": "docker/19.03.4 go/go1.12.10 git-commit/9013bf583a kernel/5.10.10-051010-generic os/linux arch/amd64 UpstreamClient(Docker-Client/19.03.4 \(linux\))"
```
which is not valid according to [spec](https://www.json.org/json-en.html)
specifically, string: "<any codepoint except " or \ or control>*"

Go 1.13 and up enforce import paths to be versioned if a project
contains a go.mod and has released v2 or up.
The current v2.x branches (and releases) do not yet have a go.mod,
and therefore are still allowed to be imported with a non-versioned
import path (go modules add a `+incompatible` annotation in that case).
However, now that this project has a `go.mod` file, incompatible
import paths will not be accepted by go modules, and attempting
to use code from this repository will fail.
This patch uses `v3` for the import-paths (not `v2`), because changing
import paths itself is a breaking change, which means that the
next release should increment the "major" version to comply with
SemVer (as go modules dictate).

When a given prefix is empty and we attempt to list its content AWS
returns that the prefix contains one object with key defined as the
prefix with an extra "/" at the end.
e.g.
If we call ListObjects() passing to it an existing but empty prefix,
say "my/empty/prefix", AWS will return that "my/empty/prefix/" is an
object inside "my/empty/prefix" (ListObjectsOutput.Contents).
This extra "/" causes the upload purging process to panic. On normal
circunstances we never find empty prefixes on S3 but users may touch
it.

The OCI distribution spec allows implementations to support deleting manifests
by tag, but also permits returning the `UNSUPPORTED` error code for such
requests. docker/distribution has never supported deleting manifests by tag, but
previously returned `DIGEST_INVALID`.
The `Tag` and `Digest` fields of the `manifestHandler` are already correctly
populated based on which kind of reference was given in the request URL. Return
`UNSUPPORTED` if the `Tag` field is populated.

A repository need not contain any unique layers, if its images use only layers
mounted from other repositories. But, the catalog endpoint was looking for the
_layers directory to indicate that a directory was a repository.
Use the _manifests directory as the marker instead, since any repository with
revisions will contain a _manifests directory.
