make prefix log output in full.log and on console with --show configurable

Prefix path

Currently log of "avocado.test" logger are prefixed with a very long path, it would be nice to make the prefix path of file configurable. This is called task.identifier in code https://github.com/avocado-framework/avocado/blob/master/avocado/core/messages.py#L377
To get something from :

1-project/tests/setup/setup_flash_test.py:SetupFlashTest.test_setup_isFlash_nominal: 2026-01-13 08:55:51,519 avocado.utils.process process          L0475 DEBUG| [stdout] [297/1044] Building C object zephyr/subsys/net/CMakeFiles/subsys__net.dir/lib/sockets/socketpair.c.obj

to :

2026-01-13 08:55:51,519 avocado.utils.process process          L0475 DEBUG| [stdout] [297/1044] Building C object zephyr/subsys/net/CMakeFiles/subsys__net.dir/lib/sockets/socketpair.c.obj

by the way this behaviour is different between logger avocado.job does not include prefix path for example.

Prefix content

Currently this is hardcoded here (https://github.com/avocado-framework/avocado/blob/master/avocado/core/utils/messages.py#L253)

fmt = "%(asctime)s %(module)-16.16s L%(lineno)-.4d %(levelname)-5.5s| %(message)s"

It could be nice to make it also configurable

--show usage

I would like to use this kind of command line:

avocado --show :INFO run tests/setup/setup_activated_test.py --failfast

But currenlty logs are flooded by avocado.job at beginning and I wonder if it should be DEBUG level instead
