Add ability to ignore list order when comparing objects

[bettyand]

Description

Currently, Lists with the same elements in a different order are considered changed and therefore audited. For my team's use case, this change is not meaningful and adds clutter to our audits. We would like to be able to ignore order when comparing lists.

Proposed solution

add an ignoreListOrder boolean to AuditorEventConfig. add a method to ObjectDiffCheckerService to use instead of the simple previousValue != updatedValue check, something like this:

using hashCodes to sort and compare means it doesn't matter what type of element is in the list

Alternatives considered

this could be the default, but some users might care about list order so i think it's better to have it be configurable. i also thought about trying to let users pass in a comparison method through the configuration, but that would leave more room for error and may not be needed.
