Fixes and maintenance

Resolved issues in this release

Property values containing the percent character (%)—for example, in proxy passwords—are now passed directly without modification. You no longer need to escape % as %%. (OA-64300)
Fixed a resource leak where HTTP responses weren't properly disposed of during non-200 status codes. (INFOBS-9713)
Fixed an issue with Kubernetes platform monitoring so that Kubernetes events with Namespace as involved object kind now correctly have the Namespace as source entity. (INFOBS-9531)
