OpenAPI support

[iskitsas]

Implement a new module which will read OpenAPI (Swagger) documents and will create test scenarios for flexbench.

This module can be built in 2 phases:

1. Read the OpenAPI document, and with the help of ML and nodejs generate a bash script with curl commands that make sense and with input data for curl commands that look like they have been provided by a Software QA Engineer to test (eg. if testing a submission of a registration form, provide data that look real, and exercise happy and sad flows)
2. Read the OpenAPI document, and with the help of ML create ready to use .flex scenarios, to be consumed by our server and desktop app

Successfully implementing phase 1, means we can offer the module as a standalone script through npm for general usage, no depending on a flexbench app

If needed we will split the work in smaller issues, keeping a reference (in comments) with this issue as a parent. For any split issue do not forget to add the labels:
