Chain ACKs publish bundle

[mhofman]

Describe the bug

The publishBundle provided by agoric-cli in the deployPowers (added in #4975) seem to not handled errors correctly:

• The publish can fail with an account sequence mismatch error, and there is no retry logic
• The publishBundle seem to be fire and forget, claiming success even in the presence of errors

To Reproduce

Steps to reproduce the behavior:

1. Checkout https://github.com/Agoric/testnet-load-generator/tree/mhofman/publish-bundle
2. Run the loadgen: SDK_SRC=/path/to/agoric-sdk ./start.sh

Expected behavior

Successful loadgen

Additional context

@kriskowal mentions that we should handle both failures of sending the bundle to the chain, and failure of the bundle to be installed on the chain.
