replace the current yeilding pipeline, to resemble mordern day middleware

[David Rundle]

the current pipeline way of supplying middleware tasks is a little brittle

implement the middleware as demo'ed here (do not need to supply the IoC support) http://dbones.github.io/2017/02/Middleware-is-the-new-aop/

[David Rundle]

might move this to be internal (no adding new tasks/actions)
