Raise Google API HTTP send timeout from 2 minutes to 60

By default, httpclient will set a send timeout of 120 seconds,
which causes any Google HTTP request to be interrupted every 2 minutes.

The Google API client uses resumable uploads so that if a transfer
request is interrupted, it can retry where it left off. The client
will retry at most N + 1 times, which means transfers can only last as
long as this (N + 1) * send timeout. We raise this timeout to an hour
since otherwise transfers can only last 8 minutes (4 * 2 min) before
being interrupted.
