Commit timeout

[faddat]

What is the purpose of the change

Reduce osmosis block times to about three seconds.

• feat: fast tm-db #2009 compliments this and has been used by notional and others since evmos upgraded. Those using it and not are pretty strikingly visible here:

The trouble with the tm db branch is it is enormous and it is now very different from the mainline. I don't know if it will ever become the mainline. Here is the branch:

tendermint/tm-db#237

This is still very much draft work, and doesn't help with wall clock time at all yet.

Brief Changelog

• make init.go set the commit timeout to two seconds
• fix the commit timeout in root.go to two seconds

Please note that these are the only changes that have been made. I am treating additional changes that may be needed because of shorter block times is out of scope for this PR. I also think that it's possible that there are not additional changes needed.

Testing and Verifying

The best test of this code will be to run it on the osmosis test net. It has not yet been tested like that.

This LGTM! Have you been trying it out on mainnet, whats the precommit inclusion like on blocks you produce?

Actually yes, and in fact it turned out to work so well that we didn't notice the difference
