[#771] Use named loggers instead of directly calling logging

[stevenvdb]

In most places, python-irodsclient uses named loggers (e.g., logger = logging.getLogger(__name__); logger.debug(...)). This is nice because it allows to separate logging done by the Python code using the irodsclient from the logging of irodsclient itself. There were however still a few cases where the root logger was used and this PR corrects that.

Changes look good! I've made an issue for this, #771, so @stevenvdb if you could link to that issue into the commit message, (we usually just prepend a string like [_771] for instance, referencing the issue) I think we can approve it fairly quickly.

Looks good to me.

@d-w-moore Awaiting your approval.

@stevenvdb Please update the commit message to use a # instead of _. For instance:

[#771] Use named loggers instead of directly calling logging

Thanks for your contribution!

@stevenvdb - I can see a commit with the updated commit message here: stevenvdb@f2f18dd But that commit does not appear to be on any branch, or at least it's not on the branch for this PR. Can you please push that commit to the use_named_loggers branch in your fork so that this PR is updated? Then, we can merge this. Thanks.
