header
containers/image is the dominant client library to interact with
registries.
It detects which authentication to use based on the WWW-Authenticate
header returned when pinging "/v2/" end-point. If we didn't return this
header, then creds are not used for other write-protected end-points.
Hence, the compatibility fix.
Since we want to conform to dist-spec, sometimes the gc and dedupe
optimizations conflict with the conformance tests that are being run.
So allow them to be turned off via configuration params.
Upstream conformance tests are being updated, so we need to align along
with our internal GC and dedupe features.
Add a new example config file which plays nice with conformance tests.
DeleteImageManifest() updated to deal with the case where the same
manifest can be created with multiple tags and deleted with the same
digest - so all entries must be deleted.
DeleteBlob() delete the digest key (bucket) when last reference is
dropped
As the number of repos and layers increases, the greater the probability
that layers are duplicated. We dedupe using hard links when content is
the same. This is intended to be purely a storage layer optimization.
Access control when available is orthogonal this optimization.
Add a durable cache to help speed up layer lookups.
Update README.
Add more unit tests.
Now that we're GCing blobs on delete/update manifest, we should lock the
blob queries so that they don't race with each other.
This is a pretty coarse grained lock, there's probably a better way to do
this.

Clients today expect the repo to clean up if there are unused blobs, not to
manually delete things they think are unused. Let's do that, and use
umoci's code to do it since it's tested and works.
v2: also run GC on update as well as delete
v3: fix up error return paths needing two args

Previously, CheckManifest() was not checking for repo not found
condition and would default to 500 status code.
Add the check now to return 404.
Fixes issue #74
- that errors be returned a certain way using the new NewErrorList()
method and the string enum constants
- allow for full blob upload without a session with repo name and digest
Fixes issue #67.
As per dist spec, DELETE of a image manifest can only be done with
digest as <reference> param. Previously, tags were being allowed as
well. This is not conformant to the spec.
New options added to configuration file to reference a public key used
to validate authorization tokens signed by an auth server with
corresponding private key.
Resolves#24

dist-spec community is now maintaining its own conformance suite hosted
at https://oci.bloodorange.io which over time will be more complete.
This makes zot's compliance cli superfluous. Hence, deprecating the cli.
However, we keep the unit tests itself though.
