Tiered storage does not (yet) support schema operations (except create) and a few other bits of functionality, such as verify.

This ticket is to extend the tiered python hooks to include stub functions for these methods that return success without doing anything.  This won't work for tests that rely on those methods doing something useful. But there are a bunch of tests that just want to know that the method worked and don't examine the effects.  

Functions that I know need stubs include:

• SESSION::drop() [Already implemented]
• SESSION::rename()
• SESSION::verify() [Already implemented]
• SESSION::salvage()
• SESSION::compact()
