> We have a number of query options which are set on connection string and are applied to every request executed on top this connection. This includes "distributedJoins", "enforceJoinsOrder", "colocated", etc.. This is not very flexible because user have to construct different connection strings for different set of options. 
> JDBC API mitigates this problem with {{Statement.unwrap()}} method. Ultimately it allows to case {{Statement}} object to vendor-specific class where any additional methods could be exposed. 
> Let's create public wrappers for out statements where it would possible to set necessary options. When set, we will add them to query requests thus overriding connection string counterparts.
