Comment 23 for bug 1591327

I've done some investigation while environment is deployed:

1. ceilometer-polling agent initialized nova-client before Nova completed all starting processes, and in discovery instances we see `internalURL not found`
2. The same error notification is received on all request for nova-api till Nova starting process continues.
3. When Nova start works proper ceilometer nova-client keeps returning errors and such behavior is changed approximately in one hour after service was started.

Any manipulations like restarting polling service or reverting environment fix this issue. It is seems that starting ceilometer-polling agent explicitly after all nova services will be a fix.
