Public bug reported:

Description
===========
nova-mange placement audit command always fails because the target resource provider is not found
~~~
# nova-manage placement audit --resource_provider dbba1bf7-6e97-4dcb-8d4c-37fe36633358 --verbose
Resource provider with UUID dbba1bf7-6e97-4dcb-8d4c-37fe36633358 does not exist.
Error: non zero exit code: 127: OCI runtime error
~~~

However the resource provider record actually exists in Placement.

Looking at placement access log, the command is sending request with
&uuid=<uuid> instead of ?uuid=<uuid>
