erasure-code: ec-cache-agent in firefly-x/stress-split-erasure-code

Immediately after the Firefly installation, create an erasure code pool
behind a replicated cache pool. Run deep-scrub on all OSD while a rados
task runs. After upgrading half of the cluster (MON and OSD), run a
rados task again also deep-scrub in parallel.
