Description

As @phadej suggested in https://github.com/GetShopTV/swagger2/pull/100#issuecomment-296771754 we should add MFunctor instance for DeclareT for completeness.

Note that we can't define MMonad instance (similarly to StateT).

Contributor guide

Research direction
Understand the MFunctor type class from the mmorph package and implement the hoist method for DeclareT. Look at similar instances for StateT as a reference.
