    Ensure the zone records quota is enforced

    When creating a recordset, we only assert the recordset specific quota
    is respected, ignoring the zone record quota.

    This updates the code to enforce the records quota as well as excludes
    the managed records when calculating the quota. Also, the submitted
    records are taken into account when testing the quota. For example, if
    the total number is 10 and the limit is 11 (the total must be less
    than the quota), submitting an update to a recordset to lower the
    number of A records from 5 to 3 should be allowed.
