Conformance Pack for FedRamp not deployable in GovCloud

[jpSimkins]

I tried to use: Operational-Best-Practices-for-FedRAMP.yaml from here in CloudFormation in GovCloud and it will not deploy due to a couple reasons.

1. Some metrics are not on GovCloud.

2. Property validation failure: [Value of property {/InputParameters} does not match type {String}]

This is the same issue when trying to deploy the same conformance pack in Config in the AWS console.

I recommend adding a check to see if the region is a GovCloud region. I added this to my template so I can use the same template across partitions but I am stuck with the inputParameters not being a string.
