Add termination policy customization in helm chart (#2255)

Currently default pod termination logs go to /dev/termination-log.
With CI we need to change customize path somewhere to /var/log for
exporting logs with the kind export logs command.
Setting FallbackToLogsOnError as termination policy for skaffold.
