Calculates the overdue timestamp (<em>overdue_ts</em>) based on the
current timestamp and the intervals for polling and poll-overdue:
<p>
<em>overdue_ts = now_ts - pollingInterval -
pollingOverdueInterval</em>;<br>
<em>pollingInterval</em> and <em>pollingOverdueInterval</em> are
retrieved from tenant-specific system configuration.

@return <em>overdue_ts</em> in milliseconds since Unix epoch as long
value
