Problem: cosmos-sdk is not updated to v0.46

[Terra854]

Version 0.46 of cosmos-sdk has been released. Therefore, i would like to propose that the project's cosmos-sdk be updated asap while v4 is still in alpha. That way, we will be able to implement minimum commissions which has been requested by multiple validators for a long time now.

Should be similar to the cronos upgrade: crypto-org-chain/cronos#578
The main blocker right now is: cosmos/ibc-go#1653

Also, wasmd needs to upgrade to cosmos-sdk v0.46.
