by default, if for a property the required is not set to false then the value is true.

as a result, we distribute a CSAR that has properties with no value but there require true.

this causes the parsing to fail when using the the OPENSTACK parser.

example:

service-57431726F7e64a30Ae52-template.yml
node “d7c95393-7396-4d74-a3b0 0” needs to define required parameter of the properties 'nf_naming_code' ...... because the
required default is true. If it is false, node properties required false should be setted. change the node.yml definition
3.5.8 Property definition default: true
