System Monitor plugin scripts for active checks should use the JOC Cockpit REST web service including authentication

Feature

• The article How to perform active checks with a System Monitor such as Nagios/op5 explains the use of System Monitor plugin scripts to check availability of a Master and Agent.
• The plugin scripts use http to connect directly to a Master/Agent. This represents an insecure configuration and should be improved like this:
  • Both plugin scripts address the JOC Cockpit REST Web Service, not the Master/Agent directly.
  • The plugin scripts optionally use https
  • The plugin scripts use authentication and should be used with a role that includes minimum permissions for this task. Optionally a new role should be created for this purpose and should be added to the installer.
