Proposal to change the log file name

[ndelvalle]

The current log file name is: test_2020-08-08--00-48-52.log and is created using this function:

pub fn create_job_name(repository: &str) -> String {
    let repository = repository.replace("/", "-");
    let now = Utc::now().format("%Y-%m-%d--%H-%M-%S").to_string();
    format!("{}_{}", repository, now)
}

There was not research on best patterns to name a log file and what would be best for Subilo, so I'm creating this issue to track possible new formats.
