Simple DataSource extension for easy execution of query

[PatilShreyas]

Currently what I need to do is

    dataSource.connection.use { connection ->
        NormQuery().query(
            connection,
            NormParams(param1=value1, param2=value2, paramN=valueN)
        )
    }

So here basically I manually need to use connection and NormParams for passing parameters to the query.

If we declare method like

    fun <P, R : Any> DataSource.runQuery(query: Query<P, R>, params: P.() -> Unit): R {
         val result = ... // Get result data class
         return result
    }

Then we can use Norm generated classes like...

    fun addSomething() {
        val result = dataSource.runQuery(NormQuery()) {
            param1 = value1
            param2 = value2
            paramN = valueN
        }
    }

Here param and response result will be generic.
