Werk #4460: BI aggregations: Now able to configure additional message for each rule result

When configuring a rule, you can now set an optional message, which will be displayed beside the rule result. In earlier versions, a rule result was OK, CRIT, etc. The new option allows you to provide an additional text for each state.

So the result now may look like CRIT, only 70% of servers are up.

This additional information is also shown in the check plugins check_bi_aggr and check_bi_locals.py.
