Decentralization of configuration parameters phase 1

[turmelclem]

Content

Introduce a new crate called mithril-protocol-config to retrieve information about the Mithril Network (like epoch settings and aggregator features).

This crate contains a new trait, MithrilNetworkConfigurationProvider, and a first implementation calling Aggregator REST API. (in the future, for the purpose of decentralization, a new implementation will be created reading the Cardanao chain).

Crate mithril-signer use this new trait instead of using its internal AggregatorClient.
