Botond Dénes eac597d726 Add preferred and last replicas to the signature of query()

preferred_replicas are added to the parameters and last_replicas are
added to the return type. The preferred replicas will be used as a hint
for the selection of the replicas to send the read requests to. The last
replicas (returned) are the replicas actually selected for the read.
This will allow queries to consistently hit the same replicas for each
page thus reusing readers created on these replicas.
For convenience a query() overload is provided that doesn't take or
return the preferred and last replicas.

This patch only adds the parameters and propagates them down to
query_singular() and query_partition_key_range(). The code to actually
use these preferred-replicas will be added in later patches.
This reason for separating this is to reduce noise and improve
reviewability for those functional changes later.
