Deploy on Optimism Testnet

[guidiaz]

• Most probably, a new rpc-gateway may be required as to properly estimate a tx's gas price (and limit)
• Perhaps (unprobable), some specific implementation of WitnetRequestBoard contract may be required
• Deploy and publish first pfs:
  • [x] OP/USDT-6 ?
  • [ ] USDT/USD-6 ?
  • [ ] OP/USD-6 ??
