JobScheduler Startscript uses HTTP port for commands

Current Situation

JobScheduler Startscript uses TCP port for commands

Desired Behavior

Since 1.11 a HTTP port is required.
So, JobScheduler Startscript uses HTTP port with "localhost" for commands.

• The URL is http://localhost:[http_port]/jobscheduler/master/api/command
• Startscript reads http_port attribute from ./config/scheduler.xml
• Startscript considers cli option -http-port which beats the ./config/scheduler.xml
• HTTP client is implemented with Java
