Add Batcher Cost Metric

Description

This PR adds four panels showing the accumulated spending costs by the Batcher for creating and canceling tasks.

• One for the total accumulated cost (CreateTask + cancel transaction) over a specified a time range.
• One for the accumulated cost of cancel transactions only, over a specified a time range.

• Two more, with the historical versions of the previous ones:

How to test

To easily send a cancel transaction, you can go to batcher/aligned-batcher/src/retry/batcher_retryables.rs:165 and edit the code to return an error:

// timeout to prevent a deadlock while waiting for the transaction to be included in a block.
    let _result = timeout(Duration::from_millis(transaction_wait_timeout), pending_tx)
        .await
        .map_err(|e| {
            warn!("Error while waiting for batch inclusion: {e}");
            RetryError::Permanent(BatcherError::ReceiptNotFoundError)
        })?
        .map_err(|e| {
            warn!("Error while waiting for batch inclusion: {e}");
            RetryError::Permanent(BatcherError::ReceiptNotFoundError)
        })?
        .ok_or(RetryError::Permanent(BatcherError::ReceiptNotFoundError));
    Err(RetryError::Permanent(BatcherError::ReceiptNotFoundError))
