Running on Preview and Preprod

[michalrus]

The problem

The default configuration files are only defined for Mainnet and the (now dead) Sanchonet:

• /processes/omnibus/omnibus.toml,
• /processes/omnibus/omnibus-sancho.toml,
• /processes/replayer/replayer.toml,
• /processes/replayer/replayer-sancho.toml.

The build.rs scripts also assume we’re either running on Mainnet or the (now dead) Sanchonet:

The solution?

I could try to tweak them for the testnets, but, IMO, Preview and Preprod are popular enough to also include them in the repository.
