Command line flag parity for agoric publish with agd tx swingset install-bundle

[kriskowal]

What is the Problem Being Solved?

We created agoric publish as a porcelain for submitting a bundle to the chain and watching for whether the SwingSet controller accepted or rejected the artifact. It originally shelled out to agd and we converted it to use CosmWasm instead. However, we do not have feature parity with agd when it comes to interacting with keychains, and it lacks other flags like --gas, so we’re still recommending agd.

Description of the Design

Revert to shelling out to agd and thread all of the agd CLI flags through. Keep the part that watches the chain for the acceptance of the bundle. Also verify ahead of time that the file contains JSON and has a valid ID since the chain can’t publish a usable update to agoric follow :bundles in vstorage unless it can parse and identify the bundle.
