unified both local and s3 ImageStore logic into a single ImageStore
added a new driver interface for common file/dirs manipulations
to be implemented by different storage types
refactor(gc): drop umoci dependency, implemented internal gc
added retentionDelay config option that specifies
the garbage collect delay for images without tags
this will also clean manifests which are part of an index image
(multiarch) that no longer exist.
fix(dedupe): skip blobs under .sync/ directory
if startup dedupe is running while also syncing is running
ignore blobs under sync's temporary storage
fix(storage): do not allow image indexes modifications
when deleting a manifest verify that it is not part of a multiarch image
and throw a MethodNotAllowed error to the client if it is.
we don't want to modify multiarch images

before syncing an image we first check if it's already present in our storage
to do that we get the manifest from remote and compare it with the local one
but in the case of syncing docker images, because the conversion to OCI format is done while
syncing, we get a docker manifest before conversion, so sync detects that local manifest and
remote one are different, so it starts syncing again.
to overcome this, convert remote docker manifests to OCI manifests and then compare.

Moved boltdb to a driver implementation for such interface
Added CreateCacheDatabaseDriver in controller
Fixed default directory creation (boltDB will only create the file, not the dir
Added coverage tests
Added example config for boltdb
Re-added caching on subpaths, rewrote CreateCacheDatabaseDriver
Fix tests
Made cacheDriver argument mandatory for NewImageStore, added more validation, added defaults
Moved cache interface to own file, removed useRelPaths from config
Got rid of cache config, refactored
Moved cache to own package and folder
Renamed + removed cache factory to backend, replaced CloudCache to RemoteCache

- Digests were represented by different ways
- We needed a uniform way to represent the digests and enforce a format
- also replace usage of github.com/google/go-containerregistry/pkg/v1
with github.com/opencontainers/image-spec/specs-go/v1
