Although the Octavia itself works fine, I think there should not be "down" agents on the initial deployment (that causes false positives in Nagios, reporting the agents down, but in reality they are up - and I need to remove these "duplicate" agents to remove the alert).

Adding ~field-high as this is happening on the customer env which is expected to be handed over next week.

FWIW, the issue is transient and doesn't occur every redeployment - I was able to get a deployment without network agents in DOWN state some time ago + we have a workaround (as Octavia itself works), so I think we can remove field-high atm.
