Executing Stored Procedure Ignores lowercase_schema_reflection

[rodpaddock]

The execute_procedure method ignores the lowercase_schema_reflection when mode is :dblib

I looked into the code and it appears the :odbc setting handles lower casing column names when executing a stored procedure. The :dblib setting looks like it is missing this feature.

The adapter is written so that it favors no low level connection mode feature set. This keeps the code cleaner and more adaptable to further connection modes, like we did for ADONET and possibly a future JTDS mode. The lower case is a good example of this. The primary place we implement this feature is in the schema reflection for columns. So basically just doing this with ruby and sql.

Stored procedures could do this with some ruby in the #execute_procedure method to force the keys to downcase, but I am not sure if I am open to this patch. We have some major changes coming to our stored procedure implementation for OUTPUT parameters and I am not sure if forcing a lower case schema is appropriate here. For now, I saw this is going to be one of those roll your own parts of legacy schema.

Wont fix as it would break existing behavior. The #execute_procedure is an adapter gravy addition and if something ever makes its way into core, we may coerce/lower.
