  - Fix data type properties declaration

    According to TOSCA Network properties definition the keyname 'ip_version:' should have Integer as valid_values rather than String
    Where the keyname 'count:' is declared as a String type the default value should be String rather than Integer
    Fix misspelled ONAP types 'onap.datatypes.monitoring.measurementType' and 'onap.datatypes.monitoring.managedObjectDNsBasic'
    Fix the keynames 'upstream:' and 'downstream:' as both are declared as a String type the valid_values should be String rather than Integer
