There seems to be flakyness in python pickout up stdout from qsub

Removed snapshot as it is no longer used
Removed iens in one constructor as it is no longer part of the class

Updated some type hints
Formatted a few lines
Added some asserts and if guards

Written assuming there will be a global option to set SUBMIT_SLEEP,
but will currently pick from the selected queue system.

Also added return value to _add_realization as that is expected by other
functions

Poking an internal variable in queue, _queue_stopped. This should perhaps
be an official way in order to stop the queue from a sync context

+ mypy ignore in _legacy.py

…odule

Ensure storage state is set correctly when runs fail.

Adjust error string building

Passes test_tracking_integration

There is no need to test get_option in the driver,
and config_dict_generator is testing the slurm memory options

We don't need testing of get_options, and that
we get an LSF driver when we ask for it
