Description of problem:

When using RHEL OSP-d to deploy a small cloud (65 bare metal machines), the deployment will run out of resources and fail due to max_resources_per_stack =1000 . Increasing the value allows the deployment to succeed.

Ideally the director should be able to calculate this, if nt, set the value to at least 100000. 
 
Version-Release number of selected component (if applicable):
2015.1.0-4.el7ost

How reproducible:
every time

Steps to Reproduce:
1. Try to deploy 60+ nodes
2.
3.

Actual results:
Deployment runs out of resources and fails

Expected results:

It should just deploy out of the box.

Additional info:

Is there any additional overhead of allowing a higher count if it is not reached ?
(is some amount of system resources set aside for the given value ?)
