Executed a local network using simapp and looked for logs that seemed superfluous. This isn't by any means an exhaustive grooming, but should drastically help legibility of logs.

also, include node ID in the output (#5769) and modify NodeKey to use
value semantics (it makes perfect sense for NodeKey to not be a

## Description
Hardcode ed25519 to dialTCPFn in e2e tests.
I will backport `DefaultRequestHandler` fixes
This will be replaced when grpc is implemented.
Closes#5291. Adds a randomized testnet generator. Nightly CI job will be submitted separately. A few of the testnets can be a bit flaky, even after disabling known-faulty behavior and making minor tweaks, and the larger networks may be too resource-intensive to run in CI - this will be optimized separately.
