Conway genesis

[JaredCorduan]

In light of CIP-1694, this issue needs to be redone, so I have re-opened this issue. The conway genesis will now need to supply whatever new protocol parameters are added to conway. See #3146 .

The new parameters are:

• all the governance voting thresholds
• constitutional committee term limits
• governance action expiration
• governance action deposit (govDeposit)
• DRep deposit amount (drepDeposit)
• DRep activity period (drepActivity)
• minimal constitutional committee size
• maximum term limit (in epochs) of the constitutional committee

Additionally, the interim constitutional committee (ie what was previouosly being called GenDelegs) will need to specify expirations (of the cold key) for each member.

Create a conway genesis type containing the governance map:

newtype ConwayGenesis crypto = ConwayGenesis (GenDelegs crypto)

and use this type as the translation context:

type instance TranslationContext (ConwayEra c) = ConwayGenesis

in the Cardano.Ledger.Conway.Translation module.

Lastly, use the conway translation context to replace the existing GenDelegs map inside of the DState type.
