feat(aggregation-mode): support multiple dbs

[MarcosNicolau]

Description

Adds support for multiple databases and retry logic to the following components:

• PaymentsPoller

• Gateway

• ProofAggregator

  To enable this, a new module/struct called DbOrchestrator was introduced. It is responsible for handling retry logic and selecting the appropriate database.

1. Start ethereum package:

make ethereum_package_start

2. Start gateway

make agg_mode_gateway_start_ethereum_package

3. Start poller:

make agg_mode_payments_poller_start_ethereum_package

4. Send proofs:

make agg_mode_gateway_send_payment
make agg_mode_gateway_send_sp1_proof

5. Start proof aggregator:

make proof_aggregator_start_ethereum_package
