Made log buffer interval configurable and made it default to 0 seconds. This makes Mesos behave more as expected out of the box, outputting all lines to the log file when they are written. Unfortunately, the old default logbufsecs value of 1 didn't do this because Google Log doesn't actually flush logs this often if you aren't repeatedly writing messages (see http://code.google.com/p/google-glog/issues/detail?id=52). It might be nice to have a thread periodically flush the log until glog fixes this issue, but for now it's good to have a default behavior that's sensible.
