Indexing new providers contracts

[brunomenezes]

📄 Context

An original PR on Sunodo has an implementation for indexing new provider contracts. However, we have a lot of commonalities, and the API could index such contracts.

✔️ Solution

Add the implementation of said contracts for indexing (use original PR as a reference). Also, consider the entity diagram below for implementation.

Entity diagram

New contracts (ABI) and events of interest:

• AuthorityFactory
  • AuthorityCreated (topic)
• ValidatorNodeProvider
  • MachineLocation (topic)
  • FinancialRunway (topic)
  • Paused (topic)
  • Unpaused (topic)
• Marketplace
  • ValidatorNodeProviderCreated (topic)

New Entities:

• Authority
• ValidatorNodeProvider
• ValidatorNode

📈 Subtasks

• Add new contract ABIs.
• Add new Entities to graphQL schema.
• Generate new migrations.
• Add new handlers for topics of interest.
• Add preloaders for Marketplace to store ValidatorNodeProvider addresses
• Add test cases.

🎯 Definition of Done

• Can successfully index the AuthorityFactory, Marketplace and ValidatorNodeProvider contract events.

@tuler,
In the original PR, I saw the definition of the ReaderNodeProvider and ReaderNode entities. However, I could not see an ABI nor any reference to saving during the implementation in the main.ts when working with the block/log. Is that some initial idea forgotten to clean up, or is it missing?

Maybe it's missing. I'm not implementing reader node just yet. Focusing on validator nodes only.
