refactor(batcher): retry function

[entropidelic]

Motivation

This PR implements the retry_function(), which receives a function to be retried using exponential backoff.

Description

Modifies the batcher to use retry_function() in the following calls:

• user_balance_is_unlocked
• get_user_nonce_from_ethereum
• get_user_balance
• get_gas_price
• s3::upload_object
• listen_new_blocks()

Stops using our forked version of ethers-rs since is not longer needed.

Observations

The calls within the Batcher::new() function are not modified since in case of failure the program will panic (changes can be implemented if needed).
Also create_new_task was left for a different PR.

All modified calls use the following default parameters:

• DEFAULT_MIN_DELAY = 500
• DEFAULT_MAX_TIMES = 5
• DEFAULT_FACTOR = 2.0

How to Test

make anvil_start_with_block_time
make batcher_start_local
make batcher_send_burst_groth16

Now try killing the container running the s3 service. You should see 5 warnings separated by exponential time:

[2024-10-17T21:14:09Z WARN  aligned_batcher] Error uploading batch to s3 dispatch failure

• There are also some test in batcher/aligned-batcher/src/retry.rs

• You can also add a sleep() before the function you want to test in the batcher, and then kill Anvil before the call happens.
