I think it's temporary disabled due to transition discoverd -> 
inspector, and will be reenabled as soon as we fix the high priority issues.

Is it with ironic-python-agent, right? If so, I've noted that it always 
fails to connect to inspector. Then it is restart by systemd, and the 
second attempts succeeds. We'll have procedure in place to collect logs 
from the ramdisk, but it's not wired in yet as well. Anyway, if the 
introspection works at all, you should not be too concerned for now :)

Profile matching is in especially uncertain state right now. Thanks for 
reminder, we should start sorting out - as soon as introspection is part 
of the gate again.
