Perf measurement and profiling w/multichain

[turadg]

What is the Problem Being Solved?

Like #10511 but integrated with multichain-testing

Description of the Design

in progress

depends on

• FU multichain testing of happy path #10597

not expected to simulate mainnet (for example, due to different block times). goal: are we getting faster/slower? are we in the right ballpark?

Security Considerations

Scaling Considerations

Test Plan

Upgrade Considerations

[dckc]

we have a relevant measurement in #10618

the test takes about 32 seconds after setup.

I should also also measure blocks.

13 sec to advance

Looking at ci logs from Dec 12, 14, and 16, we're pretty consistent at 13 sec from 1st OCW evidence to completion of advancement IBC transfer.

IOU a look at blocks.

[dckc]

15 blocks - 1:30 to 2:40

From evidence to advanced seems to take 15 blocks. At 7 sec, that's 1:30. But one explorer shows 12.37 sec avg block time. At that rate, it's 2:40.
