Move handling of JWT for Conan packages into Gitlab::ConanToken.

Instead of setting the token as an instance variable override the finder
to look into Bearer and Basic authorization headers for Conan API
requests.

Instead of reusing the personal access token (and thus having it stored
locally) issue JWT that has the access token id in the payload and when
provided fetch that token and autheticate using it.

Derive JWT secret unique to Conan packages from
attr_encrypted_db_key_base_32.

Add new Conan API endpoint `/users/authenticate` that when valid
personal access tokens is provided (as password for HTTP Basic Auth)
will respond with the same access token in the response body.

For subsequent requests the token will be provided by the Conan client
as bearer in the HTTP_AUTHORIZATION header.

The downside of this approach is that the access token will be stored
locally by the Conan client in a SQLite database.

Add support for deferred links in persistent user callouts.

Closes #64341

See merge request gitlab-org/gitlab-ce!30818

Persistent user callouts now support deferred links, which are links
that can be used to dismiss the callout, and then proceed to follow
the link's original location.

This ensures that the callout dismissal is properly recorded
before the user leaves the page.

This spec needs to run as a request-style spec in order to invoke the
Rails router.

A controller-style spec matches the wrong route, and
`session['user_return_to']` becomes incorrect.
