Description of problem: On running openstack undercloud install, the command almost runs to completion but fails during post_config phase with the following error regarding mistral environment config https://gist.githubusercontent.com/smalleni/eeba1bf421b4a3c8a9790cad0d3373e8/raw/7c1807b614dfb3fc5c54037e788d5240eb75102d/gistfile1.txt

stackrc is generated and all commands such as ironic node-list, openstack baremetal import work fine but when trying to deploy overcloud, the deploy fails in less than 20s without the heat stack even being created with the following error "Environment not found [name=tripleo.undercloud-conf]" .

rerunning openstack undercloud install on the same failed node, we didn't see this issue. The issue seems to be not checking if osprofiler_web was initialized, so having a 'if osprofiler_web:' should solve this. However, https://github.com/openstack/python-mistralclient/commit/d655e010b87c60cb62475324edfe3893c34ef711 already addresses this but doesn't seem to be included in the latest package.


Version-Release number of selected component (if applicable):
OSP 10 - See 'if osprofiler_web:' missing in /usr/lib/python2.7/site-packages/mistralclient/api/httpclient.py in RC puddle too.

How reproducible:
Intermittent, not very reproducible

Steps to Reproduce:
1. Install undercloud
2.
3.

Actual results:
stackrc is generated but overcloud deployment fails when attempted in less than 20s with error "Environment not found [name=tripleo.undercloud-conf]" 

Expected results:
Undercloud should be installed and overcloud deployment should succeeed.
