Invalid credentials not reducing cloud success rate

I was making credentials changes to interact with an Openstack cloud as a different user. I deleted the current credentials before adding new ones (oops).

I was checking the cloud statistics on the dashboard to make sure that things were working as expected, and nowhere did this problem show itself until I clicked in to understand why there were no build slaves being created.

The errors were being reported into the cloud statistics, but in a way that didn't reflect as a slave creation failure, meaning that the percentages on the dashboard were not changing, as they didn't seem to be counted as attempts to create a slave.
