[Rdo-list] Can't delete network from neutron

[Ihar Hrachyshka]

Hi David,

Your issue is very interesting. I thought port cleanup was fixed with:

https://review.openstack.org/#/c/127357/

And the fix is included in Juno. It would be interesting to see whether 
there are any routers in your database, and whether there are any 
objects in 'routerports' table (those are expected to be purged once a 
router is deleted).

If you need help in identifying commands that are needed to get the 
needed info, please tell me.

Thanks,
/Ihar
