/**
 * Custom migrations should be defined in this function. This will be called with the CLI 'migrate:v2-beta-testnet' command.
 * Migrations could be written to run in parallel, but if you want contract addresses to be created deterministically,
 * the migration should be written to run synchronously.
 * @param provider  Web3 provider instance.
 * @param artifactsDir The directory with compiler artifact files.
 * @param txDefaults Default transaction values to use when deploying contracts.
