Potential IndexOutOfBoundsException in RoundRobinHostHandler

[wajda]

In highly loaded systems, an ever incrementing member variable current in the class RoundRobinHostHandler would numerically overflow within a quite realistic time horizon (months). It would cause the index variable to become negative resulting in an IndexOutOfBoundsException to be thrown.

final int index = (current++) % size;
Host host = hosts.getHostsList().get(index);

See: https://github.com/arangodb/arangodb-java-driver/blob/v6.16.1/src/main/java/com/arangodb/internal/net/RoundRobinHostHandler.java#L62:L63

Changing the current variable type to long would practically solve the issue.
