Set the period in milliseconds.
<br>
The provider will periodically send notifications every period milliseconds.
The period can thus be seen as a sort of heart beat.<br>
<br>
<b>Minimum, Maximum, and Default Values:</b>
<ul>
<li>The absolute <b>minimum</b> setting is 50 milliseconds.<br>
Any value less than this minimum will be treated at the absolute minimum
setting of 50 milliseconds.
<li>The absolute <b>maximum</b> setting is 2.592.000.000 milliseconds (30 days).<br>
Any value bigger than this maximum will be treated at the absolute maximum
setting of 2.592.000.000 milliseconds (30 days).
<li>The <b>default</b> setting is 50 milliseconds (MIN_PERIOD).
</ul>

@param periodMs
The publisher will send a notification at least every period_ms.
@return this (fluent interface).
