[Feature Request]: Run parallel threads with multiple mobile devices on browserstack

[mabouamer-93]

Problem:
We have just bought a browserstack license to run our tests on multiple mobile devices, and our project is build on SHAFT framework.
Browserstack can run test on multiple mobile devices using browserstack.yaml file.

Feature required:
It will be great if SHAFT supports using parallel threads on browserstack

Here is the documents for browserstack how to configure the yaml file
