LDAP performance checker

[Arran Cudbard-Bell]

Frustrated by the lack of any LDAP performance checker that was simple to configure,
easy to build, and actually worked, I wrote this:

  https://github.com/arr2036/ldapperf

  https://github.com/arr2036/ldapperf/archive/v0.1.tar.gz

Maybe someone else will find it useful.

With a set of 10,000 objects, with random object retrieval (using full DN and base scope) 
with OpenLDAP 2.4.39 + LMDB on a 12 core E5-2697 v2 @ 2.7Ghz with Ubuntu 14.04,
24 threads on the server, 50 threads on ldapperf i get around 45,000 TPS.

Retrieving the same object multiple times (possibly taking advantage of some sort of query
cache) I get between 60,000-66,000 TPS.

Now you can prove (or not) that FreeRADIUS is the bottleneck :)
