Prepare network removal from `CardanoDbBeacon`

[Alenar]

Content

This PR ensure that the upcoming removal of the network field from the CardanoDbBeacon won't cause incompatibility in the network even with yet to update node.

Entites Adaptation

• Add a network field to Snapshot entity: since the snapshot is very strongly tied to the network it's based on, this ensure that this metadata remain easily available.
  • Added by the CardanoImmutableFilesFullArtifactBuilder when a snapshot is build using the network from the configuration
  • Migrate existing Snapshot artifact in the aggregator database signed_entity table

Messages Adaptation

• Add network field to SnapshotMessage, SnapshotListMessage, and SnapshotDownloadMessage
• Add CardanoDbBeaconMessagePart: a duplicate of the actual CardanoDbBeacon but with a optional network.
  • Used in CertificatePendingMessage, SnapshotMessage, SnapshotListMessage, and SnapshotDownloadMessage
• Add SignedEntityTypeMessagePart: a duplicate of the actual SignedEntityType, needed because half of the usages of the CardanoDbBeacon are through the SignedEntityType
  • Used in CertificateMessage, CertificateListMessage, CertificatePendingMessage, and RegisterSignatureMessage
• Source the network value from a different source than the CardanoDbBeacon to ensure that its removal won't impact the messages:
  • From the certificate metadata network for: CertificateMessage, CertificateListMessage
  • From the configuration for: CertificatePendingMessage, RegisterSignatureMessage
  • From the new network field when converting snapshot entities to SnapshotMessage, SnapshotListMessage, or SnapshotDownloadMessage

[!WARNING] The new network field is mandatory in SnapshotMessage, SnapshotListMessage, or SnapshotDownloadMessage. This mean that a upgraded client is not compatible with not upgraded aggregators.

Services Adaptation

• Make the CardanoImmutableDigester compute the beacon hash that's added its result by itself instead of relying on the CardanoDbBeacon code
  • It's code is copied from CardanoDbBeacon::compute_hash and adapted to take a parametrized network so it don't rely on the soon removed CardanoDbBeacon::network
  • This ensure that digest produced by the CardanoImmutableDigester won't change after removing the network from the CardanoDbBeacon

Other

• Make the compression_algorithm and cardano_node_version mandatory in the SnapshotMessage and SnapshotListMessage. They were added as optional in order to avoid breaking changes with yet to upgrade nodes, since it was back in distribution 2337 enough time as passed to ensure that all nodes are upgraded and won't break with those fields marked as mandatory.
