In Requests transport treat ``timeout`` stricly as a transport timeout, while the total allowed method execution time can be set with an optional ``max_allowed_time`` argument.

Towards https://github.com/googleapis/google-cloud-python/issues/10137
This PR makes a distinction between the Requests transport timeout, i.e. the
timeoutparameter, and the total allowed execution time for therequest()method, i.e. themax_allowed_timeargument. These two are not mixed together anymore.In other words, if
timeoutis passed in (set to, say, 60 seconds) and an underlying request takes longer, but the times between the bytes received by the socket are all under 60 seconds, theTimeoutGuardshould not kick in and cause a timeout error (the cause of Storage #10137).TimeoutGuardis only affected bymax_allowed_time, which isNoneby default, making the guard a no-op.
