Fix broken debug_level

Currently, debug_level is documented as a way to change
the debug output level for both masters and nodes.

debug_level does not currently have any effect.

This commit removes debug_level from openshift_facts
and properly sets openshift_master_debug_level and
openshift_node_debug_level to the value of debug_level
specified in the inventory.

This commit also reorganizes some set_fact tasks
needed during master upgrades to put all work-around
set-facts for undefined variables in one place, allowing
for easier cleanup in the future.  This includes an
entry for openshift_master_debug_level.

Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1500164
