[BCI-2714]: adds sncast scripts

[chris-de-leon-cll]

Adds sncast Scripts

Overview

Please see the ticket here for more details! tl;dr this PR adds support for using sncast to interact with the data feed example contracts on Starknet testnet OR a local container running starknet-devnet-rs.

Primary Changes

• bumps starknet foundry from v0.18.0 to v0.21.0
• bumps cairo to v2.6.3
• modifies ./ops/scripts/devnet-hardhat.sh such that the container version can be configured (snfoundry v0.21.0 needs an rpc v0.7 endpoint, and the script defaults to using rpc v0.6)
• adds the following data feed sncast scripts (all located in ./examples/contracts/aggregator_consumer/scripts/src/test-consumer:
  • deploy_test_consumer (deploys MockAggregator and AggregatorConsumer)
  • read_decimals
  • read_latest_round
  • set_latest_round
• adds helper commands in the Makefile to simplify script setup and execution
• updates the README.md file in ./examples/contracts/aggregator_consumer
  • adds details on how to run the sncast scripts on both testnet and a local starknet devnet container using the helper commands in the Makefile
    • describes what commands exist
    • explains how to use the commands
    • explains what each commands does
    • explains how to read the output of the commands
• simplifies the consumer.cairo contract
  • removes read_decimals (not needed for new docs)
  • removes read_latest_round (not needed for new docs)
  • adds read_answer (needed for new docs)
  • adds set_answer (needed for new docs)
  • updates the test cases in test_consumer.cairo accordingly

We already call cleanup on startup:

chainlink-starknet/ops/scripts/devnet-hardhat.sh

Line 11 in 38b10b2

bash "$(dirname -- "$0")/devnet-hardhat-down.sh"

[chris-de-leon-cll]

Good catch! I'll modify the script

[archseer]

You can define account = "$ACCOUNT_NAME" in the toml config under the default profile, then we don't need to specify --account everywhere

[chris-de-leon-cll]

Done!

• In snfoundry.toml the account name is now configurable through an environment variable which is set automatically in the Makefile
• The Makefile is now the only place where the account names for devnet and testnet are defined - it is not hardcoded in any other place

[archseer]

Let's define accounts-file to be in the current directory and gitignore it. That way we're not leaving global artifacts on user's system

[archseer]

(only for devnet though)

[chris-de-leon-cll]

Done!

• In snfoundry.toml, I made accounts-file configurable through an environment variable which is set automatically in the Makefile
• The Makefile is now the only place where the accounts-file paths for devnet and testnet are defined - it is not hardcoded in any other place
• For devnet, the accounts file is called accounts.json and it lives at the same level as snfoundry.toml. It is currently gitignored using a pre-existing rule in the .gitignore file in the repo's root directory
• For testnet, the accounts file is unchanged (~/.starknet_accounts/starknet_open_zeppelin_accounts.json)

[archseer]

How about a devnet and a testnet profile in sncast, then removing --url flags and hardcoding the account name on devnet?

[chris-de-leon-cll]

Done!

• In snfoundry.toml, there is now a devnet profile and testnet profile each with their own RPC URLs
• In the Makefile the commands now use the --profile flag
• The Makefile sncast commands now require an argument NETWORK which is used to determine which profile a.k.a which network to run the script on
