Description

Ticket moved to GitHub: "pulp/pulpcore/1823":https://github.com/pulp/pulpcore/issues/1823


During sync we query list of tags present in the repo.

Pagination support is available for Tags API, we need update our sync code to cope with this change.
We'd need to check the `Link` header if it is present in the response headers.
For more docs check [0]
For Pulp2 implementation check [1]

Sync from quay should do it.
