* Add setup script for dev basics like users and stores
I'm using and extending this script for setting up the basics after I erase my dev containers. Once you clean out everything with `cd BTCPayServer.Tests && docker-compose down --volumes --remove-orphans && docker-compose up dev` you otherwise have to recreate everything manually. This gives you ...
- An admin user with unrestricted API key
- One additional user per default role
- Store 1: Satoshis Steaks with Hot Wallet and Internal Node (and all users assigned to that store)
- Store 2: Nakamoto Nuggets with Hot Wallet and Merchant LND Lightning node (and all users besides Guest assigned to that store)
- Nakamoto Nuggets also gets Cart and Keypad apps
- Store 3 with External Lightning based store with Customer LND Lightning node
## Sample output
