Public bug reported:
Pike
DVR + L3_HA
L2population enabled
Some of our L3 HA routers are not working correctly. They are not reachable
from instances.
After deep investigation, I've found that "HA port tenant <tenant id>" ports
are in state DOWN.
They are DOWN because they don't have binding information.
They don't have binding information because 'HA network tenant <tenant_id>'
network is corrupted.
I mean it does not have provider:network_type and
provider:segmentation_id parameters set.
The weird thing is that this network was OK and worked but in some point
in time has been corrupted. I don't have any logs from this point in
time.

I've found that all working networks have revision_number = 3 and all not
working networks have revision_number = 5.
When HA network tenant network is corrupted ALL L3-HA routers in a particular
tenant are not working.
Is there any way to fix this without removing all existing L3-HA routers in
this tenant?
Unfortunately I can't find any code responsible for "HA network tenant"
updating or modification so I hit a wall in my debugging process.
It is probable that network has been corrupted during some automatic
network resources provisioning using Heat stack but I can't reproduce
this.
