Checkmk Werk 14334: Add ID to title of host custom attributes on exports

ID: 14334 Title: Add ID to title of host custom attributes on exports Component: Multisite Level: 1 Class: Bug fix Version: 2.2.0i1 If views with multiple columns "Host custom attribute" were exported, e.g. as JSON or CSV, the title for each attribute was "host_custom_variable". This was now changed to "host_custom_variable_ID" to make it easier to distinguish. Maybe an adjustment of an automated export is needed.
