As first discussed at https://bugzilla.redhat.com/show_bug.cgi?id=1347305 since we now run keystone under wsgi::apache, deploying on a multinode host gives very poor performance, because the current default for puppet-keystone is to have 1 worker [1] and ::processorcount threads [2].
We should be able to set both of these as parameters, as jistr points out in the BZ keystone::wsgi::apache::workers and keystone::wsgi::apache::threads.
Since keystone under wsgi is a mitaka thing we will also need to backport this. However, the backport is going to be significantly different because master has composable keystone service whereas mitaka doesn't.
Review for master incoming momentarily thanks.
