BREAKING CHANGE: repository paths are now specified under a new config key called "repositories" under "accessControl" section in order to handle "groups" feature. Previously the repository paths were specified directly under "accessControl".
This PR adds the ability to create groups of users which can be used for authZ policies, instead of just users.
{
"http": {
"accessControl": {
"groups": {
Just like the users, groups can be part of repository policies/default policies/admin policies. The 'groups' field in accessControl can be missing if there are no groups. The permissions priority is user>group>default>admin policy, verified in this order (in authz.go), and permissions are cumulative. It works with LDAP too, and the group attribute name is configurable. The DN of the group is used as the group name and the functionality is the same. All groups for the given user are added to the context in authn.go. Repository paths are now specified under a new keyword called "repositories" under "accessControl" section in order to handle "groups" feature.

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
Closes https://github.com/project-zot/zot/issues/615

Periodically poll registries and pull images according to sync's config
Added sync on demand, syncing when clients asks for an image which
zot doesn't have.

Some LDAP servers are not MT-safe in that when searches happen with binds
in flight leads to errors such as:
"comment: No other operations may be performed on the connection while a
bind is outstanding"
Add goroutine-id in logs to help debug MT bugs.
