[1.1] Have a way to externally inject a python script

[raju-apple]

From chip-certification-tool created by raju-apple: CHIP-Specifications/chip-certification-tool#587

For some semi-automated test cases where we have a user-prompt for a reboot test case with the text "Reboot your DUT" We should allow the vendor / ATL to write a reboot.py script and that script should be able to provide the "Y" or whatever the TH is waiting for once it's done to continue further . So this in short can convert a few of the semi-automated tests into fully automated ones.

This is a very generic ask but something that we have been putting off for a while , could you start looking into this and see if you have any ideas on this use case ?

On further analysis we dropped this feature.
