-----

* (EE only) Bug-fix: If you created a ArangoSearch view on Satellite-
Collections only and then join with a collection only having a single
shard the cluster-one-shard-rule was falsly applied and could lead to
empty view results. The Rule will now detect the situation properly,
and not trigger.

* (EE only) If you have a query using only satellite collections,
now the cluster-one-shard-rule can be applied to improve
query performance.

* (Enterprise Edition only): added query option `forceOneShardAttributeValue`
to explicitly set a shard key value that will be used during query snippet
distribution to limit the query to a specific server in the cluster.
