> In RU from HDP 2.2  -> 2.3.0.0, Storm will not be rolling, so the upgrade pack still
needs instructions to deactivate and kill running topologies before upgrading Storm, and to
rebuild the topologies after.
> In 2.3.0.0, Storm's defaults.yaml will have the property storm.meta.serialization.delegate
set to backtype.storm.serialization.GzipThriftSerializationDelegate, so as long as Ambari
doesn't override the property, the RU from 2.3.0.0 to 2.3+ will be rolling. So the upgrade
pack from Dal to Dal will not need these manual confirmations.
> To test this out, deploy HDP 2.3.0.0, then perform and RU to HDP 2.3+, and verify the
topologies are still running
