httperf wrapper for benchmarking CouchDB

Features:

* Results sent to CouchDB and printed in TSV
* Creates wsesslog files dynamically using random data for document writes and _all_docs for reads
* Lots of knobs: session counts, document size, request rate, etc
* httperf session work logs are attached to results for replaying later


License:

This code is available as Open Source Software under the MIT license.


Usage:

$ gem sources -a http://gemcutter.org
$ gem install baracus
$ baracus /path/baracus.yml

Suggestions:

* Set "ulimit -n 65535" before running baracus
* Change FD_SETSIZE to 65535 in /usr/include/bits/typesizes.h before compiling httperf
* For tests with more than 1000 sessions increase MAX_SESSION_TEMPLATES in gen/wsesslog.c before compiling httperf
