`readProtocolParametersSourceSpec` should be able to retrieve the `ProtocolParameters` by querying local node

[carbolymer]

readProtocolParametersSourceSpec is supposed to derive a ProtocolParameters value from either JSON encoded ProtocolParameters file or a ShelleyGenesis file. The problem is the ProtocolParameters has had fields deprecated and added as we've transitioned between the eras. The scope of the change:

1. Deprecate the option to derive the ProtocolParameters from the ShelleyGenesis as this is incorrect for the reason I gave above.
2. In all instances where readProtocolParametersSourceSpec is used to generate a ProtocolParameters value, include the option to use the local state query protocol (i.e query the local node) to retrieve the current ProtocolParameters value.

Additional tasks:

• Consider re-using connection when querying the node
