Update Templates to Make Partition-Agnostic

[ferricoxide]

Problem Description:

Templates may not be sufficiently portable if ARNs hardcode the :aws: partition-element into them (won't work in specialty-regions like aws-cn). See AWS::Partition pseudo-param documentation.

Expected Behavior:

All templates should work in all AWS partitions

Actual Behavior:

The make_jenkins_ELBv1-pub-autoscale.tmplt.json template will fail if not launched into the default/commercial AWS region

Fix recommendation:

Update enumerated template-files to update all "arn:aws:... string-literals to something more like:

            {
              "Fn::Join": [
                ":",
                [
                  "arn",
                  { "Ref": "AWS::Partition"},
                  …,
                  …
                ]
              ]
            }
