infrastructure-playbooks: Get Ceph info in check mode

In the `set osd flags` block, run the Ceph commands that gather information
from the cluster (and don't make any changes to it) even when running in check
mode.

This allows the tasks that depend on the variables set by those tasks to
succeed in check mode.
