(QA-777) Allow beaker to deploy a split PE on version 3.2

3.2 includes a large database schema change. Part of the schema
migration is to validate availability of free space. On split
configurations, the dashboard upgrader will ask the user to make sure
there is sufficient space on the database node. We need to answer
"yes" to this from Beaker.
