Deployment script with OpenZepplin deploy

[calj]

With this draft I'm getting the following error from OpenZepplin API:

  request: { path: '/v2/deployments', method: 'POST' },
  response: {
    status: 500,
    statusText: 'Internal Server Error',
    data: {
      message: "Cannot read properties of undefined (reading 'contracts')"
    }
  }
}

We can give a try with the hardhat plugin, it's supposed to be easier to use. https://www.npmjs.com/package/@openzeppelin/hardhat-upgrades
