iotests: Add test for QMP event rates
This test verifies that the rate-limited QMP events are emitted at a maximum rate of 1 per second as defined in monitor_qapi_event_conf in monitor.c It also checks that QUORUM_REPORT_BAD events generated from different nodes are kept in separate queues so they don't mask each other.
