Investigate on ICS29 fee middleware

[thomas-nguy]

In order to bring cosmos tokens to cronos, we need a fee mechanism to cover the cost of maintaining relayers

ICS29 fee middleware in ibc-go seems still WIP, but worth to have a look and experiment

I can work on investigating the ICS29 and how could I experiment with this? @thomas-nguy

[thomas-nguy]

Maybe the first task will be to look at the repo, try to understand how does it work and how far are we from completion by reading the integration/unit tests

Then try to setup a local instance with the module

okay.

I have updated the description with the spec link

ok. I have been reading though this spec and now need to review the code.
