What does this PR do?

A variety of changes to migrate the Demo Org to DDR

Description of the Change

• The dashboard_lists update was swallowing errors, removed try/except to raise them instead. These failures will now be marked as failures rather than successes.
• The synthetic_tests can depend on these rum_applications but we didn't support them as a resource. Added.
• Some spans_metrics resource have an element automatically added to the group_by list. Had to add a nullable list to the base resource to support this.
• There's a type of synthetics_global_variables resource that is secure, when is_fido is True we can't pass in a value field (not documented in the synthetics API docs)
• Many synthetic_tests depend on synthetics_mobile_applications which have synthetics_mobile_applicaitons_versions. These were both added. The version require using pre-signed URLs so there's a lot a code around that.
• The resource handler was comparing an unprepared version of the destiantion resource, we prepare it now to handle the nullable list values.
