Implement audit log in mysql

[hakasapl]

There should be an audit log in mysql stored in a table with the following fields:

• id Primary auto increment value
• timestamp second precision timestamp in UTC
• operator the user doing the operation
• operator_ip IP of the operator
• action_type the action type. Could be
  • user_added when user gets created
  • sshkey_modify when ssh keys get modified for a user
  • etc....
• recipient the user which the action is done upon (might be the same as the operator in many cases)

The boostrap file for the dev environment sql will need to be updated along with the code.

The following events should trigger an audit log entry:

• All the setXYZ methods in UnityUser
• Anytime a user logs in, log their IP
• Anytime a request is approved/denied in either the admin panels or the pi management panel
• Anytime a cluster notice is added in the admin page
• Anytime a content management is modified in the admin page
