Align messages golden master tests

[Alenar]

Content

This PR align all mithril-common messages golden master test to the same test model:

• A const CURRENT_JSON string containing a exhaustive example of json currently exchanged between nodes
• A golden_message_current method that returns the representation of the CURRENT_JSON using the current structure
• A test_current_json_deserialized_into_current_message test that check that de-serializing the CURRENT_JSON into the current structure yield the output stored in golden_message_current
• For each supported backward compatible previous version of a structure (example based on the CertificateMessage):
  • A copy of the previous version structure as it was before the backward-compatible change, the copy is suffixed with the last version of the openapi before the change, ie: CertificateMessageUntilV0_1_32
  • A golden_message_until_open_api_X_Y_ZZ method that returns the representation of the CURRENT_JSON using the previous structure (also suffixed)
  • A test_current_json_deserialized_into_message_supported_until_open_api_X_Y_ZZ test that check that de-serializing the CURRENT_JSON into the previous structure yield the output stored in golden_message_until_open_api_X_Y_ZZ.

LGTM 👍

Maybe the naming actual could be replaced with current or latest?
