Idempotency for Audit Configuration is not working

[Warkdev]

Hello,

The idempotency of this API call is not working properly: https://github.com/IBM-Security/ibmsecurity/blob/master/ibmsecurity/isam/base/audit_configuration.py

The issue being that the json_compare is often providing back false due to the misalignment between the config lists.

To solve this problem, the following _check method does the sorting:

1. At the top, add:

from operator import itemgetter

2. In the check method, replace:

        "config": config,

by

        "config": sorted(config, key=itemgetter('key'))

3. And add it as well later in the retrieved config:

aud_cfg['config'] = sorted(aud_cfg['config'], key=itemgetter('key'))

These changes will make sure that both lists are sorted on the 'key' element prior comparing them.
