Issue: refactor(permissions): Give access to connector view group in operation groups

Currently `connector_label` is not visible in payments page of control-center. This is because, the payment retrieve API doesn't send the `connector_label`. As it is a big change in the payments flow, we are providing access to connector list API, so that control-center can fetch the data from there.
