Check_MK Werk 5983: docker_node_images: Fixed mixups between images of same repository and different tags

ID: 5983 Title: docker_node_images: Fixed mixups between images of same repository and different tags Component: HW/SW Inventory Level: 1 Class: Bug fix Version: 1.6.0i1 The number of containers was not counted per image because the tag information was not handled correctly in all cases. Some containers don't explicitly state "repository:tag" but only "repository" as their image, depending on the "docker run" call. Check_MK is now falling back to "latest" tag in this case.
