Description

In order to side-load contracts to Sidecar, we want to add the following features:

• Detecting an upgradeable contract when we process transaction logs
  • This will not be applicable to EigenLayers' core contracts but only to side-loaded contracts to automatically update contract ABIs
  • This function is not being called in this PR
• Pulling ABIs from IPFS (main source)
  • The contract metadata needs to exist in IPFS in order for us to pull ABIs. Added 10 seconds timeout during HTTP Get
  • TODO: add a fallback source to pull the data from Etherscan

Non-feature updates:

• Added AbiFetcher as a new input to ContractManager
• All tests, except pipelineIntegration_test and restakedStrategies_test, should use a non-paid quiknode url address
• Updated the ethereum NewClient parameter with http.Client to accept mocked client

Fixes #223
