Code Issues Proposed changes

Do not barf stack trace if stats DB is missing

Browse Source 
This can happen if devstack fails to run, but we still run the post
tasks. Also could happen if some sort of hybrid job configuration
does not run all of devstack but we still end up running post jobs.

Just warn to stderr and assume no DB info.
