Adding the records of user is added to a group or removed from the group to the audit log

Description

Currently, the audit logs only record the following action.

• Changes to the system configuration of Crowd
• Adding or removing applications, updating application configuration
• Adding or removing directories, updating directory configuration

It will be better if the audit log is recording action such as user-created, user added to a group or remove from a group, and etc. This will allow the admin to have a better history overview on what is updated and who update it,
