Deploy `testing-mainnet` network

[jpraynaud]

Why

In order to test early the scaling of the signature/proof generation with the mainnet, we want to create a testing-mainnet environment that is manually deployed with the test network deployment workflow.

What

Setup a new testing-mainnet network to perform scaling measures of the Cardano transactions signature/proofs.

How

• [ ] Setup a new testing-mainnet network in the test network deployment workflow:
  • [x] 1 aggregator (restore with Mithril snapshot)
  • [x] 1 signer (restore with Mithril snapshot)
  • [x] No SPO authentication
  • [ ] Authentication on the aggregator
  • [x] Genesis the network
  • [ ] Network produces certificates consistently
• [ ] Activate the Cardano transactions signature on the network
