[Feature Request] Allow arbitrary setup/teardown code for the Wai Application

[donatello]

I have a situation where to create an instance of the Wai Application, I need to run an action:

mkApp :: IO Application
mkApp = do 
  -- allocate database pool (or something else)
  pool <- mkPool
  someApp pool

Currently there seems to be no way to test this application with tasty-wai as testWai does not allow such setup.

Is this a reasonable feature request to add? Something like:

testWaiWith :: IO Application -> IO () -> TestName -> Session () -> TestTree
testWaiWith acquireApp releaseApp testName $ do ...

Is there a recommended way to do this in a different way if this feature does not make sense?

I have no intention to add any functionality to this library, and the only maintenance I intend to do is cabal metadata revisions and maybe new releases when necessary.
Maybe @mankyKitty is interested in maintaining it, but otherwise we might need to look into handing it over to someone.

This seems related to my PR: #16. I don't know the current maintenance state of this package, but feel free to use my fork if you still need this functionality @donatello
