Often we want to build a test collection that substitutes different
sequences of tasks into a parallel/sequential construction. However, the
yaml combination that happens when generating jobs is not smart enough to
substitute some fragment into a deeply-nested piece of yaml.
Instead, make these sequences top-level entries in the config dict, and
reference them. For example:
tasks:
- install:
- ceph:
- parallel:
- workload
- upgrade-sequence
workload:
workunit:
- something
upgrade-sequence:
install.restart: [osd.0, osd.1]
