ZF-7514: Sqlsrv driver does not support Windows auth

Description

Windows authentication does not use username/password and these options should optional.

Uid + password: Sql server authentication No uid + no password: Windows authentication

Both or none, not one.

Adapter should be changed to override Abstract adapter _checkRequiredOptions() method to remove username/password requirements.
