always use whitespace around statements
Add subdir-objects to configure.ac
Add tags to config file

"tagged". Tags make it possible for different addresses to occupy the same
portion of the hash ring, so that moving statsrelay shards or changing IP
addresses will not result in every key being rehashed.
