* 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.

1. Move existing CVE DB download generator/task login under the cve package
2. Add a new CVE scanner task generator and task type to run in the background, as well as tests for it
3. Move the CVE cache in its own package
4. Add a CVE scanner methods to check if an entry is present in the cache, and to retreive the results
5. Modify the FilterTags MetaDB method to not exit on first error
This is needed in order to pass all tags to the generator,
instead of the generator stopping at the first set of invalid data
6. Integrate the new scanning task generator with the existing zot code.
7. Fix an issue where the CVE scan results for multiarch images was not cached
8. Rewrite some of the older CVE tests to use the new image-utils test package
9. Use the CVE scanner as attribute of the controller instead of CveInfo.
Remove functionality of CVE DB update from CveInfo, it is now responsible,
as the name states, only for providing CVE information.
10. The logic to get maximum severity and cve count for image sumaries now uses only the scanner cache.
11. Removed the GetCVESummaryForImage method from CveInfo as it was only used in tests

fix(authz): fix isAdmin not using groups to determine if a user is admin.
fix(authz): return 401 instead of 403
403 is correct as per HTTP spec
However authz is not part of dist-spec and clients know only about 401
So this is a compromise.

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

* fix: remove inline GC and set a default value of gc interval
- remove inline GC
- add a default value of GC interval
- run the GC periodically by default with the default value if no interval provided
- generate GC tasks with a random delay(0-30s) between
- add IsReady() method to scheduler.TaskGenerator interface

BREAKING CHANGE: The functionality provided by the mgmt endpoint has beed redesigned - see details below
BREAKING CHANGE: The API keys endpoint has been moved - see details below
BREAKING CHANGE: The mgmt extension config has been removed - endpoint is now enabled by having both the search and the ui extensions enabled
BREAKING CHANGE: The API keys configuration has been moved from extensions to http>auth>apikey
mgmt and imagetrust extensions:
- separate the _zot/ext/mgmt into 3 separate endpoints: _zot/ext/auth, _zot/ext/notation, _zot/ext/cosign
- signature verification logic is in a separate `imagetrust` extension
- better hanling or errors in case of signature uploads: logging and error codes (more 400 and less 500 errors)
- add authz on signature uploads (and add a new middleware in common for this purpose)
- remove the mgmt extension configuration - it is now enabled if the UI and the search extensions are enabled
userprefs estension:
- userprefs are enabled if both search and ui extensions are enabled (as opposed to just search)
apikey extension is removed and logic moved into the api folder
- Move apikeys code out of pkg/extensions and into pkg/api
- Remove apikey configuration options from the extensions configuration and move it inside the http auth section
- remove the build label apikeys
other changes:
- move most of the logic adding handlers to the extensions endpoints out of routes.go and into the extensions files.
- add warnings in case the users are still using configurations with the obsolete settings for mgmt and api keys
- add a new function in the extension package which could be a single point of starting backgroud tasks for all extensions
- more clear methods for verifying specific extensions are enabled
- fix http methods paired with the UI handlers
- rebuild swagger docs

This change introduces OpenID authn by using providers such as Github,
Gitlab, Google and Dex.
User sessions are now used for web clients to identify
and persist an authenticated users session, thus not requiring every request to
use credentials.
Another change is apikey feature, users can create/revoke their api keys and use them
to authenticate when using cli clients such as skopeo.
eg:
login:
/auth/login?provider=github
/auth/login?provider=gitlab
and so on
logout:
/auth/logout
redirectURL:
/auth/callback/github
/auth/callback/gitlab
and so on
If network policy doesn't allow inbound connections, this callback wont work!
for more info read documentation added in this commit.

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.

currently different subpaths can only point to same root directory only
when one or both of the storage config does not enable dedupe
different subpath should be able to point to same root directory and in
that case their storage config should be same i.e GC,Dedupe, GC delay
and GC interval

whenever we make a request that contains header apart from CORS allowed header, browser sends a preflight request
and in response accept *Access-Control-Allow-Headers*.
preflight request is in form of OPTIONS method, added new http handler func to set headers
and returns HTTP status ok in case of OPTIONS method.
in case of authorization, request contains authorization header
added authorization header in Access-Control-Allow-Headers list
added AllowOrigin field in HTTPConfig this field value is set to Access-Control-Allow-Origin header and will give zot adminstrator to limit incoming request.
