Checkmk Werk 11276: jira notification: fix issue creation

ID: 11276 Title: jira notification: fix issue creation Component: Notifications Level: 1 Class: Bug fix Version: 1.7.0i1 Creation of Jira issues sometimes failed because the field 'labels' is not existing. Jira Service Desk does not have the 'labels' field by default, but Jira Software does. With this change, the labels field will only be set if the WATO rule for 'labels' is activated. If 'labels' is activated but not value is defined it will use the default labels 'monitoring'.
