The `var_event_record_qps.var` doesn't match the type specified in the `yamlfile_value` template

The [var_event_record_qps.var](https://github.com/ComplianceAsCode/content/blob/stabilization-v0.1.64/applications/openshift/kubelet/var_event_record_qps.var) does not match the type specified in the following OVAL:

https://github.com/ComplianceAsCode/content/blob/4bac3653b762e50eb5a9d0786a1873bdd0113d5a/shared/templates/yamlfile_value/oval.template#L63

The template needs to be updated to accept the type of the variable as input and default to string if there is nothing defined.

This causes a warning to be produced in the OpenSCAP and the results can be unknown.
