options for http and https for indicating which network interfaces the JobScheduler should listen to are supported

Current Situation

The JobScheduler listens to all available network interfaces when using http and/or https.

Desired Behavior

The options

• http_port
• https_port

are supported for indicating which network interfaces the JobScheduler should listen to when using http and https.
They can be configured in the ./config/scheduler.xml

<spooler >
    <config http_port  = "localhost:40444" https_port = "myHost:48444">
    <!-- some other elements -->
    </config>
</spooler>

• The value of http_port or https_port can have also a hostname or an ip address.
• The state element in the answer of a <show_state/> request contains the attributes http_port and https_port how they are configured.
• The answer of ./jobscheduler/master/api contains the fields httpPort and httpsPort how they are configured.

Maintainer Note

A http port setting is required -> at least http_port="localhost:40444"
