Removes Oozie password override from HDP 2.1 stack
When an Ambari Blueprint is exported from a running cluster
based on the HDP 2.1 stack, and including Oozie, an Oozie
password will be included in the exported Blueprint.
This is incorrect behavior, since no password data should
be available in the exported Blueprint. The Blueprint
processing code relies on the HDP stack definitions in
order to determine which fields are passwords.
This patch addresses this problem by removing the Oozie
password field form the HDP 2.1 stack definition. The HDP
2.0.6 stack (which is a parent of the 2.1 stack) already
includes the correct metadata for this password field, such
that the Blueprint processor will keep this field out of
an exported Blueprint as expected. Since there is no need
to override this property in the 2.1 stack, the correct
metadata can be inherited from the 2.0.6 stack.
