refactor: faster

[Reecepbcups]

Summary

Make Interchaintest fast like zooooooooooooooomies.
NOTE: this requires PollForProposalStatus delta time to be increased to account for faster blocks (else proposals are still in vote period)

This PR is currently just slop, adding things as I find / can improve

• Also does a little logger touch up to fix a visual bug

Benchmarks

IBC 6 nodes + relayer

go clean -testcache && go test -timeout 3000s -run ^TestLearn$ github.com/strangelove-ventures/interchaintest/v8/examples/ibc -v

Time to beat:
 - Before this PR: 103.31s
 - With faster blocks (in this PR) & faster relayer polling: 70.39s / 67.03s 
 - Without startup Locks: 60 / 62.8s
 - Misc caches (59 / 61s)

IBC-Go simd (v8.0.0) 1 val, build then exit

go clean -testcache && go test -timeout 3000s -run ^TestSingleValBenchmark$ github.com/strangelove-ventures/interchaintest/v8/examples/cosmos -v

Time to beat:
- 11.74s (11.335517782s build)
- 10.45s (faster poll on Status to start)
- 10.14s / 10.02s (cached Exec container)
- 8.85s (cache isSDKv47 genesis call)
- 8.12s (key addressCache, doubles for getting mnemonics from keys created to the keyring directly with CreateKey)

Build (including relayer setup) takes 50s of the total 60s test time. If we can speed up the ic.Build we could get test down. May require the pre starting relayer PR (backend wise for chain configs, then start once we have a block 1/2)

Should also see if there is anything we can do rly side to speed up the IBC queries, connections, etc. this seems to be one of the last optimizations I can think of

[Reecepbcups]

#1153 is probably the next big performance improvement. Getting relayers to auto provision for planned testing is ideal, lot of dead time waiting.

We already know the chain configs to chains add, rly keys restore, and rly paths new (config). Then we just rly tx link as soon as the chain is at height capable.

Must allow relayers pre ic.Build() standalone

ideas from Andrew:

• sleep infinite then just exec into the container on start
• next issue may be docker volumes

[Reecepbcups]

export genesis state after IBC start, then can load back from that in future runs

I have been taking things from this PR and putting into others as it seems right.
