Code Issues Proposed changes

Increase interface detach polling period

Browse Source 
The gate has started failing due to interface detaches timing out.
Examining the logs, it looks like Nova's interface detach retry takes about
6s to run one attempt. Heat, on the other hand, does 10 retries at 0.5s
intervals. So if Nova has to retry then Heat will fail.

Increase Heat's polling interval to make it more likely that if Nova
succeeds, Heat will see it.
