Comment 5 for bug 1940838

The issue is that the agent is reporting at 5 minute intervals, not 30 seconds.

This change[1] in TripleO changed it to 300s, instead of the neutron default which is 30s.

<hjensas> ksambor: ^^ Any reason to up the report interval from 30s (the default) to 300s? https://opendev.org/openstack/neutron/src/branch/master/neutron/conf/agent/common.py#L112
<hjensas> Tengu: ^ that explains the bug.
<ksambor> hjensas, yah it was to small for bigger/more dense deployments with ovn

It seems the longer interval makes sense for OVN so we should try to find a way to reduce the interval specifically for ironic-neutron-agent instead of reverting it.
