Add example for logging in python3.8

Hi,

Can you also add logging for python38 cloud functions since by using default logger all logs are mapped without any severity level.

Hi @nitishxp,

Thanks for reporting this. We're aware of the issue and working on resolving it internally (though we're not yet sure how long that will take).

(Assigning to @joelgerard since they're the primary point-of-contact for this.)
