[feature] E2E tests & Indexer improvements

core ref: b75e9f982c7361c8349ee2569bbe9fe546b752bb

Describe your changes

• Adds caching functionality to RPC reads (object reads and view function reads).
• Introduces a gRPC connection pool for PTBClient connections.
• Updates indexing logic to include rewind / replay ability. This is useful when binding takes place after the event that needs to be indexer (in testing scenarios).
• Misc updates to ops to match updated contracts.
