Change default local ovs connection timeout

Browse Source 
Large number of flows can cause local ovs connection
timeout. Ultimately getting succeed will be better
than a retry or fullsync.

In order to improve heavy load ovs agent restart success rate, instead
a retry or fullsync, the native driver ``of_connect_timeout`` and
``of_request_timeout`` are now set to 300s. The value does not have side
effect for the regular pressure ovs agent.
