feat(l2): config eth client through .toml (lambdaclass#2510)

**Motivation**

Here we want to be able to configure some constant values in our L2.
These changes aim to improve flexibility in the L2 and provide better
control.

**Description**

* Added `elasticity_multiplier` to `BuildPayloadArgs` and passed it to
`calculate_base_fee_per_gas`.
* Incorporated `elasticity_multiplier` into `BlockProducer`.
* Introduced new fields (`max_number_of_retries`, `backoff_factor`,
`min_retry_delay`, `max_retry_delay`) in `EthClient`.

Closes lambdaclass#2479
