configure polling intervals

Building on the examples in basic example, wakeup server before mounting, testing mounts, unmount before mount and status notification commands we will now discuss polling intervals.

macmounter launches one thread per section in every config file. This thread will re-poll every RECHECK_INTERVAL_SECONDS by default. By default this is set to 300 seconds (5 minutes).

However you can configure repoll based on the state of the mount. For instance, if the ping failed, you can repoll every, say, 600 seconds (10 minutes). If the mount failed, you can poll every, say 60 seconds (2 minutes). If the mount is successful you can repoll every 420 seconds (7 minutes).

If not specified, the default for RECHECK_INTERVAL_SECONDS is 300 seconds. The default for RECHECK_INTERVAL_SECONDS_PING_FAILURE, RECHECK_INTERVAL_SECONDS_MOUNT_SUCCESS, RECHECK_INTERVAL_SECONDS_MOUNT_FAILURE is whatever is set for RECHECK_INTERVAL_SECONDS.
