e83999ae0d helm: relax Content-Type checks
OCI registries are moving towards a more generic artifact storage
mechanism. In short-term, at the very least support helm charts.

026b009dbb compat: when in "world-readable" mode, return the WWW-Authenticate
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.

b1f882e1b8 conformance: align with upstream conformance tests
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

25f5a45296 dedupe: use hard links to dedupe blobs
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.

dfe023225f pkg/api: use a rwlock when accessing storage
The original patch used a mutex, however, the workload patterns are
likely to be read-heavy, so use a rwlock instead.

94afc30661 routes: lock everything that modifies blobs
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.

6e494942d4 routes: CheckManifest should return 404 when repo is unknown
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

964af6ba51 compliance: be compliant with dist-spec compliance tests
dist-spec compliance tests are now becoming a part of dist-spec repo
itself - we want to be compliant

pkg/api/regex.go:
	* revert uppercasing in repository names

pkg/api/routes.go:
	* ListTags() should support the URL params 'n' and 'last'
	  for pagination

	* s/uuid/session_id/g to use the dist-spec's naming

	* Fix off-by-one error in GetBlobUpload()'s http response "Range" header

	* DeleteManifest() success status code is 202

	* Fix PatchBlobUpload() to account for "streamed" use case
	  where neither "Content-Length" nor "Content-Range" headers are set

pkg/storage/storage.go:
	* Add a "streamed" version of PutBlobChunk() called PutBlobChunkStreamed()

pkg/compliance/v1_0_0/check.go:
	* fix unit tests to account for changed response status codes

We have noticed that very intermittently zot returns a 500 when copying
blob data. This is likely happening due to a io.ErrShortWrite

a57f085749 compliance: cleanup compliance test code
zot ci/cd tests are too stict, so separate and relax them for compliance
tests.

Location header is set in some cases, but some clarification is needed
in URL construction.

Fix some incorrect compliance tests.

c8563d8672 routes: handle "mount blob" to remain compliant
"mount blob" was the only feature we didn't handle.
We don't fully support it yet because we don't have access control
support, but at least handle it and return something sane to remain
compliant.
