Also, in case someone has experience with adding new services to a project. Is there a general way of requesting rpms etc to be updated for the next release to support the new services? Especially for the workflows that are handled outside of the official openstack
repos.</div>

We are looking into splitting the senlin-engine into three components (senlin-conductor, senlin-engine and senlin-health-manager) and wanted to get some feedback.</div>

The main goal here is to make the components more resilient and to reduce the number of threads per worker. Each one of the components already had it's own thread</div>

pool and in theory each worker could end up with thousands of thread.<br>
