This commit adds the `OpenFunc()` function that allows us to handle how the DB connection will be opened. You can pass any function that has the same signature as `sql.Open()` and it'll use it to start the connection. The idea is to open the connections with DataDog [SQL wrapper][1] to start collecting APM metrics for our queries. [1]: https://godoc.org/gopkg.in/DataDog/dd-trace-go.v1/contrib/database/sql
Add `OpenFunc()` function
This commit adds `db/trx.QueryContext()` methods that are similar to `Query()` but accept a context (same as the STD `sql.QueryContext`). This will allow us to send tracing information to queries that will be tied to a given span. * https://golang.org/pkg/database/sql/#DB.QueryContext

Experienced a prod issue brought on by too many active prepared stmts. This driver was creating a prepared stmt for pretty much every request, this PR does a couple of things to try and address that. First, it provides a facility for limiting the prepared stmt cache size. Secondly, it introduces a flag on the datasource which can be used to not use prepared statements at all, included at the go level (see option to interpolate args here).
