Dmitry Tantsur 6e38efffea Stop aborting the process on periodic task failures
It's nice to know when a periodic task fails, but aborting the whole
process makes it fragile in the events of e.g. problems with accessing
ironic, even if transient.

Simplify the overly complex unit tests and split the dual-purpose task.
