Increase stop_grace_period for Octavia controller services

The stop_grace_period for Octavia should be greater than the longest
task executed by Octavia.
The timeout of longest task in Octavia is currently set to 10 minutes
[0].

Updating the stop_grace_period from 5min to 10min30 will prevent
failures during updates. If a really long task is running Octavia (for
instance a failover during a network outage), it will timeout in Octavia
and Octavia will exit gracefully.
