Suppose we push two identical manifests (sharing same digest) but with
different tags, then deleting by digest should throw an error otherwise
we end up deleting all image tags (with gc) or dangling references
(without gc)
This behaviour is controlled via Authorization, added a new policy
action named detectManifestsCollision which enables this behaviour

- AccessControlContext now resides in a separate package from where it can be imported,
along with the contextKey that will be used to set and retrieve this context value.
- AccessControlContext has a new field called Username, that will be of use for future
implementations in graphQL resolvers.
- GlobalSearch resolver now uses this context to filter repos available to the logged user.
- moved logic for uploading images in tests so that it can be used in every package
- tests were added for multiple request scenarios, when zot-server requires authz
on specific repos
- added tests with injected errors for extended coverage
- added tests for status code error injection utilities
