Monitoring of the event queue

[mortenwh]

The following items shall be monitored:

• Usage of create/update/delete

• Response time of every component, and total execution time

• Number of messages in the queue and number of clients

• status of the consistency of the event queue cluster (to ensure that it is not in a bad state)

memo: as Espen mentioned in a stand-up, monitoring infrastructure for mms is already in place apparently, done by Siri (we should probably talk/ask more)
