database/sql: feedback for non-DSN DB opener

There are two general ways we are considering supporting non-DSN opens.

The current CL has a Connector that is separate from the driver instance. I have a suspicion that it might be better to have the Connector be part of the Driver interface (see the CL comments).

Your feedback on this issue, CL, or the Go issue would be appreciated.

This will be added with the v2.0.0 release
