SqlRawStatementOutboundMapper Variable Binding

When SqlRawStatementOutboundMapper is initialized it can get the bind runtime option to make sh parametrized at runtime.

Example of mapper initialization in the workflow step:

hash<auto> ropts = {"bind": 1};
SqlRawStatementOutboundMapper m = get_mapper("regression-out-sql-statement", ropts);

Then values provided in runtime options (ropts), key "bind" are passed to the mappers's select statement. Resulting in for example:

select * from my_table where id = :var_1;
-- binding 1 into :var_1
