DOC: explain the relation between pool-low-conn and tune.idle-pool.shared

Disabling idle-pool sharing can result in awful performance in presence
of a not so high number of threads, because the number of available idle
connections will be shared among threads, resulting in most of them
abandonning their connections after a request is done if there are already
enough total available. This is a case where pool-low-conn ought to be
used to preserve a number of connections for each thread, but this relation
isn't obvious as is. Let's add mentions about this with both keywords.
