[ldaidone]

Created a list of new Supported Attributes required by models to implements new validator classes

[ldaidone]

List of Attributes grouped by Model with small description:

Logs
CAN_LIST_LOGS: should have Admin or SuperAdmin role.
CAN_CREATE_LOGS: should have Admin or SuperAdmin role, or own data.
CAN_FILTER_LOGS: should have Admin or SuperAdmin role, or own data.

User
CAN_CREATE_USER: should have Admin or SuperAdmin role.
CAN_DELETE_USER: should have SuperAdmin role.
CAN_SAVE_USER: should have Admin or SuperAdmin role, or own data.

Role
CAN_DELETE_ROLE: should have SuperAdmin role.
CAN_CREATE_ROLE: should have SuperAdmin role.

Optional, that will be handled in the previous list for the first cut. All of them will check roles and owner at higher level than Symfony RoleVoter.
IS_ADMIN
IS_SUPERARMIN
IS_OWNER
