Commit 1d34ef38a8 "cql3: make pagers use
time_point instead of duration" has unintentionally altered the timeout
semantics for aggregate queries. Such requests fetch multiple pages before
sending a response to the client. Originally, each of those fetches had
a timeout-duration to finish, after the problematic commit the whole
request needs to complete in a single timeout-duration. This,
unsurprisingly, makes some queries that were successful before fail with
a timeout. This patch restores the original behaviour.
Fixes#3877.
