How should the Testnet and Regtest parts of Zebra's config be structured?

[arya2]

It was mentioned in an Arborist call that disabling proof-of-work may be useful for custom/short-lived Testnets as well as Regtest in Zebra, do we want to rename the current network.testnet_parameters section to network.parameters and use it for both Regtest and Testnet?

Where would it make the most sense to put these fields? Should they apply to both Regtest and Testnet, or should they be separate so they're harder to mistakenly use with the wrong network?

It should be structured so that any serialized config deserializes to the same config, which isn't the case right now because Network is converted to NetworkKind when being serialized (though this may be easier to do in a custom Serialization impl).
