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.

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

The ui sends the header X-ZOT-API-CLIENT=zot-ui regardless of session authentication status.
In case of new sessions zot would reject the unauthenticated call on /v2 (which is used to determine
if anonymous access is allowed by the server when the header was set) expecting all users sending
this header to be already authenticated.
Since the ui received 401 from the server, it would not show the option for anonymous login.

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!

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.

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.
