Optional logger arg on jobs handler for functional styled code

[SKY-ALIN]

Example:

from datetime import timedelta
from logging import Logger
import regta

@regta.async_job(timedelta(seconds=5))
async def my_basic_job(logger: Logger):
    logger.info("A intermediate message")
    return "The final logging message"

But the old style must be supported also:

from datetime import timedelta
import regta

@regta.async_job(timedelta(seconds=5))
async def my_basic_job():
    return "The final logging message"
