Public bug reported:

Description
===========
The nova scheduler log contains some HTML (see actual result). Log files should not contain any HTML. I suspect some wrong error message parsing here.


Actual result
=============
Log Message:
----
2018-04-19 13:12:53.109 12125 WARNING nova.scheduler.client.report [req-a35b4d7e-9914-48f1-b912-27cedb6eebdd cd9715e9b4714bc6b4d77f15f12ba5a9 fa976f761aad4d378706dfc26ddf6004 - default default] Unable to submit allocation for instance 6dc8e703-1174-499d-aa9b-4d05f83b7784 (409 <html>

 <body>
  <h1>409 Conflict</h1>
  There was a conflict when trying to complete your request.<br /><br />
Unable to allocate inventory: Unable to create allocation for 'VCPU' on resource provider '322b4b21-f3ff-4d59-b6c8-8c1a9fe2b530'. The requested amount would violate inventory constraints.

 </body>
</html>)

Steps to reproduce
==================
This log line occurred after trying to live-migrate a vm from one node to another. obviously the request failed to do so.

Expected result
===============
The log line should be better formatted. for example like this:
