FU oracle operator CLI

[turadg]

refs: #10567

Description

This sets up a CLI for transaction oracle operators. It has tests but I don't expect them to pass yet.

I think this is worth landing to get the CLI scaffolded and the refactorings of agoric-cli to client-utils that support it. In particular moving the AGORIC_NET convention down to client-utils in a cli.js module and other network config helpers in network-config.js.

It will also help to DRY out the 'test-lib' code in a3p proposals that was copied from agoric-cli (e.g. rpc.js) cc @anilhelvaci

Security Considerations

agoric-cli will source its network config lookup function from another package. That's a potential supply chain weakness but it's the same org as the agoric-cli and it's very unlikely only one would be compromised if either were.

Scaling Considerations

none

Documentation Considerations

Includes CLI help and a demonstration test

Testing Considerations

I added a test that runs in CI but doesn't cause a failure so that this can live in master while we build it out

Upgrade Considerations

none

Thanks for the heads up. Will pick up #10514 tomorrow. Once that's done, it'll be easy to clear out agoric-cli pieces from test-lib

LGTM

PS: currently test-docker-build job is failing, I'm hoping this is a flake and when mergify re-run all CI tasks this job will pass
