Support to add your own PEM file for requests.verify

[rohits2290]

Defintion make_request has verify as True or False.

The requests documentation also has an option to provide a path to the pem file to verify SSL
https://requests.readthedocs.io/en/latest/user/advanced/#ssl-cert-verification.

Is it possible to add path as an option than bool responses as it's current available?

Thanks

@rohits2290 thank you for submission and being patient - I've been rather booked lately but will get back to this as soon as I can.
