Post-upgrade deprecation warnings

[mar235av]

After upgrading to Shibboleth 5.1.2, we are now seeing new deprecation warnings. These indicate things that were not deprecated in version 4.3.1, but are now marked as deprecated in 5.1.2 and will be removed sometime in the future. These represent cleanup we will need to do eventually, but not required now.

Warnings noted:
