Updated the "Using Docker for Job execution" documentation

[HelferDCSO]

The documentation article "Using Docker for Job execution" was updated so it reflects the code in line 124 turbinia/turbinia/lib /docker_manager.py.

Description of the change

The changes update the documentation article Using Docker for Job execution so that it reflects the code in docker_manager.py#L111.

The following errors occur when using the IMAGE ID instead of the REPOSITORY value:

2024-01-11 12:26:30 [WARNING] DOCKER_ENABLED=True is set in the config, but there is an error checking for the docker daemon: {0:s}
Traceback (most recent call last):
  File "/home/turbinia/turbinia/worker.py", line 198, in __init__
    check_docker_dependencies(dependencies)
  File "/home/turbinia/turbinia/worker.py", line 91, in check_docker_dependencies
    raise TurbiniaException(
turbinia.TurbiniaException: Docker image 399a772c8145 does not exist for the job psortjob. Please update the config with the correct image name

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/turbinia/turbinia/turbiniactl.py", line 1015, in main
    process_args(sys.argv[1:])
  File "/home/turbinia/turbinia/turbiniactl.py", line 694, in process_args
    worker = TurbiniaCeleryWorker(
  File "/home/turbinia/turbinia/worker.py", line 242, in __init__
    super(TurbiniaCeleryWorker, self).__init__(*args, **kwargs)
  File "/home/turbinia/turbinia/worker.py", line 202, in __init__
    ).format(str(exception))
AttributeError: 'NoneType' object has no attribute 'format'

Since the function image_exists(self, image_id) docker_manager.py#L111 doesn't use the image id but rather the image name, the documentation needed to be updated.

Changed the "Using Docker for Job execution" article in the documentation. The documentation know explains that the image name is required. Also the name of the configuration file was changed to turbinia.conf.

@hacktobeer and/or @wajihyassine These changes LGTM, but could you double check since I wasn't sure why we had the image ID instead of the image name.

Thanks all!

Thanks Aaron, let me take a look at this tomorrow.

@HelferDCSO Small feedback. Where do you see/find that the configuration filename has been changed to turbina.conf? It should be (and afaik always has been) turbinia.conf

[HelferDCSO]

@hacktobeer Your absolutely right, the file is called turbinia.conf. The documentation article currently names it as .turbiniarc.

In my PR I misspelled turbinia, which will be fixed in the next commit. I also misspelled it in my PR description. Sorry for the unpleasantries.

Some small comments, looks good, thanks for updating these docs!
