 As we can see, the `DryValidationParser::ValidationSchemaParser` goes through all the params defined in the
 schema and generates a hash. The hash is saved in the `keys` attribute of the parser.
 
 The required key in our result will be set to `true` if the field is defined as
 `required(:field_name)`, and `false` if defined as `optional(:field_name)`.

-The "x-nullable" key depends on whether we have defined the field as value, maybe or filled.
 
 For nested objects like array of objects or hash, we add a keys field with a definition
 for each field inside the nested hash.
 
 If the field is an array of primitive type, the type field will equal to the primitive type, and a
