Enable JsonPath for variable assignment in OpenAPI files

[jdiazgon]

Related to issue #489 and Pull Request #496 we would like to improve the variable assignment for the OpenAPI plug-in.

Currently, it is possible to assign extension variables to a variableAssignment, thus that we can get variables from the info part of the file and the extensions of each entity like shown on the image below:

If we implemented the possibility of using JsonPath we would be able to get attributes from any part of the OpenAPI file and not only on the info and extensions of each entity.

Tasks to do:

• Change the extension variableAssigmnent on the Matcher of the OpenAPI plug-in.
• Add the logic for using JsonPath in the InputReader.

This should not replace the extension variableAssignment. It can be more seen as an additional variableAssignment type which is more powerfull with the cost of a more complex syntax of the value.
