Creating a price authority with on-chain governance

Use Agoric SDK commit: cd agoric-sdk && git checkout mfig-oracle-management

Deploy the oracle node integration on each ag-solo:

Either a builtin oracle:

agoric deploy --allow-unsafe-plugins api/spawn.js

or for Chainlink:

INSTALL_ORACLE="Chainlink oracle" agoric deploy api/spawn.js

Take note of your node's ORACLE_ADDRESS. You will need to send it to the governance proposer.

Create a governance proposal data. Expect RemoteErrors if the in or out brands cannot yet be found:

ORACLE_ADDRESSES=agoric1...,agoric1...,agoric1... \
AGORIC_INSTANCE_NAME="ATOM-USD priceAggregator" \
IN_BRAND_DECIMALS=6 \
IN_BRAND_LOOKUP='["agoricNames","oracleBrand","ATOM"]' \
OUT_BRAND_DECIMALS=4 \
OUT_BRAND_LOOKUP='["agoricNames","oracleBrand","USD"]' \
agoric deploy api/scripts/init-core.js

Submit the proposal to the chain as described by the above command.
Wait for proposal voting to pass.
Install the Flux Notifier for each oracle that was invited in ORACLE_ADDRESSES above.

NOTE: You will need to edit api/flux-params.js to specify the correct query parameters as specified by the oracle coordinator.

AGGREGATOR_INSTANCE_LOOKUP='["agoricNames","instance","ATOM-USD priceAggregator"]' \
IN_BRAND_LOOKUP='["agoricNames","oracleBrand","ATOM"]' \
OUT_BRAND_LOOKUP='["agoricNames","oracleBrand","USD"]' \
FEE_ISSUER_LOOKUP='["wallet","issuer","RUN"]' \
agoric deploy api/flux-notifier.js

Now people should be able to query via home.priceAuthority (do the test session in README.md with pa = home.priceAuthority). Next steps are to query and gain confidence in the price feed, then possibly use it in a vault collateral proposal.
