Context

This means that cardano-cli <era> transaction commands now exist. They behave just like the legacy ones except they don't take --<era> flags by instead relying on the top-level parent to determine the era.

The change involves duplicating the transaction command structure from legacy into era-based, parameterising then parameterising TransactionCmd with era.

Legacy has LegacyTransactionCmd as well as runLegacyTx*Cmd functions which just unpacks the AnyCardanoEra and forwards the parameterised era to runTx*Cmd in era-based.

It can be observed from the CLI golden file diffs that the legacy commands remain unchanged and that the transaction command group now exists in era-based under each era.

This PR touches only 9 Haskell files, but does inevitably involve changing 139 golden files.

This PR make sit possible (although it hasn't been done yet) for conway transaction build command to have these two command line options:

                                              [--vote-file FILE]
                                              [--constitution-file FILE]

Whilst having them absent for other eras.

We'll merge this after #174

[newhoggy]

After #174 is good. I don't anticipate any large conflicts because that PR doesn't (yet) touch transactions.
