Merlin IBC Testing

This package provides helpers, for overriding components of ibctesting.

Tracked components we override:

• Adding consensus minimum fees for sent messages
• Adding SendMsgsNoCheck as a replacement for SendMsgs but without asserting the results as a success. This allows us to test errors.
• Adding a SignAndDeliver function as a replacement of simapp.SignAndDeliver that does not require an instance of testing.Testing and will return the results instead of asserting success or failure.
