Function retry 

pub async fn retry(
    transaction: &mut Transaction<'_, Postgres>,
    id: Uuid,
    by: &str,
    reason: &str,
) -> Result<bool>

Queue the job id again, now, for one more try, if it failed or waits for review, as an act of by, for reason, kept in axa_job_acts in the caller’s transaction. The act is ActKind::Retried for a failed job and ActKind::Released for one in review. Answers whether it was queued again. A job in any other state, or no such job, changes nothing and writes no act. Its last error stays until it next runs.

Errors

Fails on a database error, and with Error::NotACode when by or reason is empty, longer than MAX_REASON_CHARS, or has a line break, before anything is written.
