I'm fairly sure that having this web3 here is going to cause problems when we actually implement async, but I think it's the best solution for the moment. I believe the issue is that the middleware used to resolve an ENS address before it hit validate_address, but now validate_address is called before an ENS address is resolved. This results in an InvalidAddress error in the case where an ENS name is passed because validate_address expects a hexstring. For posterity's sake, the approach I took earlier was to add a conditional in validate_address to check that the domain was valid according to the idna spec, without actually resolving it, and then allowing the middleware to resolve it after the validation.
@marcgarreau let me know if you have a preference on approach!

I'm not too concerned about the added "cost" to the async work at this point, but this context may be long forgotten by the time its needed. Maybe a note on this issue is the way to address that?
Conceptually this is easy enough to reason about, though: if you pass an ENS name into one of these methods, the first thing that happens is a resolution check. 👍

I'm fine kicking the can down the road till async hits.

This will also fail as soon as the method is used on a ModuleV2 since the current architecture there removes self.web3 on the module class.

What was wrong?
The Eth module needs to be moved to use Method. Part 2 includes changes to eth_getBalance and eth_getCode.
Related to Issue #1568
How was it fixed?
Updated eth.py to use Method for selected methods.
