Dashboard should display JobScheduler HTTPS connection if this protocol is used

Current Situation

• The JobScheduler is configured to listen on HTTP and HTTPS ports, e.g. with ./config/scheduler.xml:
  • <configuration http_port="127.0.0.1:9180" https_port="e1-sos-berlin.ch:7013">
• In the Dashboard view the widget "Master Cluster Status" shows the correct combination, e.g. "e1-sos-berlin.com:7013"
• In the Dashboard view the widget "Standalone JobScheduler Master" shows the wrong combination, e.g. "e1-sos-berlin.com:9180"

Desired Behavior

• The JOC dashboard widget "Standalone JobScheduler Master" should not show the combination of host and port but the URL which is configured in the scheduler.xml file.
  • e.g. http://e1-sos-berlin.com:7013 for HTTP connections.
  • e.g. https://e1-sos-berlin.com:9180 for HTTPS connections.
