Avoid poll_interval to be the same as HTTP Keep-Alive timeout

Browse Source 
When OpenStack API services are behind Apache2, HTTP Keep-Alive timeout
is 5 seconds out of the box. Polling operations with the same interval
as HTTP Keep-Alive timeout can cause intermittent failures like:

Unable to establish connection to
https://nova.example.com:8774/v2.1/servers/UUID:
('Connection aborted.', RemoteDisconnected('Remote end closed connection
without response',))

Let's avoid the same value by default as Apache2's HTTP Keep-Alive
timeout.
