Keeps rule information into cache to avoid to always call the ORM for static informations. This is change allows a boost into the evaluation of exception rules by avoiding useless SQL queries to retrieve rules definitions
Before this change, the inverse relation from the exception to the records linked to the exception was read to determine if the rule should be added or removed from the rule detected for the current records. On large database with non blocking exceptions this lead to a performance issues since this issues a read of all the SO where the exception has been applied. With this change, we only read the information from the current records
