Config: Network ID is not in line with the Cardano Node config

[4TT1L4]

Problem:

• The Atlas provider configuration file does not accept the same network ID values as the Cardano node.

Solution:

• Make sure that the Atlas provider config does accept the same network ID values as the Cardano node config: preview, preprod, mainnet.

The accepted Network ID strings are listed in the NetowrkId.hs: https://github.com/geniusyield/atlas/blob/556418d9aaa767f250357f9b48c28e4160149807/src/GeniusYield/Types/NetworkId.hs#L105-L111

The problem is that the cardano node expects the network ID as "preprod", without the "testnet-" prefix. It would make things a bit easier, if atlas accepted the same networkId string as well, so we could just pass "preprod".

The current difference in the accepted network ID strings causes a bit of trouble when using Atlas with a local Cardano node.

For exampe see the following docker-compose file of the GY Smart Order Router:

• docker-compose.yml#L11
• docker-compose.yml#L40

Since the Cardano Node and Atlas uses different strings for the preprod testnet, we need to use a different value for these two components. It would make things easier, if both accepted the same values. This is the motivation for this issue.

This change is also necessary, so we could implement some simplification in the SOR docker-compose config:
