The period for job streams should be configurable

Current Situation

When creating an event in job streams the event will be created for the period 00:00-24:00 UTC. E.g. the event is created at 23:59 on the first of april then then event does not exist 2 minutes later. It is not possible to set this period to 00:00-24:00 for the local time zone.

Desired Behavior

It should be possible to configure the period for "today". There should be a central configuration item in the file scheduler.xml. The name of the parameter should be sos.jobstream_period_begin.

E.g. the value 23:00 means: today starts at 23:00 UTC yesterday and ends at 23:00 UTC today
E.g. the value 21:00 means: today starts at 23:00 Europe/Berlin yesterday and ends at 23:00 Europe/Berlin today

Example:

<spooler>
    <config http_port="40444" mail_xslt_stylesheet="config/scheduler_mail.xsl" port="4444">
        <params>
            <param name="sos.jobstream_period_begin" value="23:00"/>
.....
