* feat(cluster): support shared storage scale out
This change introduces support for shared storage backed
zot cluster scale out.
New feature
Multiple stateless zot instances can run using the same shared
storage backend where each instance looks at a specific set
of repositories based on a siphash of the repository name to improve
scale as the load is distributed across multiple instances.
For a given config, there will only be one instance that can perform
dist-spec read/write on a given repository.
What's changed?
- introduced a transparent request proxy for dist-spec endpoints based on
siphash of repository name.
- new config for scale out cluster that specifies list of
cluster members.

BREAKING CHANGE: the dist spec version in the config files needs to be bumped to 1.1.0
in order for the config verification to pass without warnings.
Also fix 1 dependabot alert for helm.

Which could be imported independently. See more details:
1. "zotregistry.io/zot/pkg/test/common" - currently used as
tcommon "zotregistry.io/zot/pkg/test/common" - inside pkg/test
test "zotregistry.io/zot/pkg/test/common" - in tests
. "zotregistry.io/zot/pkg/test/common" - in tests
Decouple zb from code in test/pkg in order to keep the size small.
2. "zotregistry.io/zot/pkg/test/image-utils" - curently used as
. "zotregistry.io/zot/pkg/test/image-utils"
3. "zotregistry.io/zot/pkg/test/deprecated" - curently used as
"zotregistry.io/zot/pkg/test/deprecated"
This one will bre replaced gradually by image-utils in the future.
4. "zotregistry.io/zot/pkg/test/signature" - (cosign + notation) use as
"zotregistry.io/zot/pkg/test/signature"
5. "zotregistry.io/zot/pkg/test/auth" - (bearer + oidc) curently used as
authutils "zotregistry.io/zot/pkg/test/auth"
6. "zotregistry.io/zot/pkg/test/oci-utils" - curently used as
ociutils "zotregistry.io/zot/pkg/test/oci-utils"
Some unused functions were removed, some were replaced, and in
a few cases specific funtions were moved to the files they were used in.
Added an interface for the StoreController, this reduces the number of imports
of the entire image store, decreasing binary size for tests.
If the zb code was still coupled with pkg/test, this would have reflected in zb size.
