Also made the driver fallback from token aware policy to round robin if both session keyspace and query keyspace are unspecified. Fixes #249

Session.Prepareselects one connection and executes a PREPARE request on it:https://github.com/mmatczuk/scylla-go-driver/blob/e2f94e15f879fea88870aa10af5ae7621c37f945/session.go#L148
It seems that the returned prepared statement ID is then stored in the Statement and reused in any connection.
However, prepared statement IDs may only be reused for connections to a single node, not the whole cluster:
