portadmin snmp timeout while saving

[Mischa Diehm]

When saving Port Configs with portadmin we have had problems especially on
cisco 2960s-stacked switches that we ran into snmp timeouts .. this local diff
fixed the problem. Maybe worth a config option??

Many thanks for discovering this!

I have added options in portadmin.conf for setting values for timeout and retries. I also adjusted the default timeout to 3 seconds, as 1 second seemed a bit optimistic.
