Pools in stretch clusters must all specify the same
CRUSH rule. No pools can use a different rule. When there
is a change in the device class, we do not even expect to update
the crush rules in a stretch cluster. Different device classes
are not supported in stretch clusters, and it's expected to be
a homogenous environment. Therefore, skip all crush rule updates
in stretch clusters.
