Checkmk Werk 15146: azure_virtualmachines: Remove resource group from summary

ID: 15146 Title: azure_virtualmachines: Remove resource group from summary Component: Checks & agents Level: 1 Class: New feature Version: 2.2.0i1 Previously, the resource group was shown in a summary of a VM service if VMs are maped to separate hosts (option 'Map data to the VM itself' in the agent config). With the werk 15261, the cmk/azure/resource_group:<group> label was added to all Azure hosts, which made this data redundant.
