ISPN-4667 Query DSL fails to load entity class in Wildfly
ISPN-4470 Remove tabs and fix other formatting issues
ISPN-4470 RemoteCache's size() method should compute size globally

* A new statistic added that shows the number of keys a cache is
primary owner for. Use that statistic, calculated cluster wide,
to count the total number of entries in the cluster for the
remote cache.
* If statistics disabled, or using Hot Rod 1.x protocol,
keySet().size() is used as fallback.
