Show the pod or instance name on an OTBI Analysis?

Summary:

We need to be able to label the header of an OTBI Analysis with which pod or instance it comes from. It can be pulled into a data model using the following query and referenced in a deep link url using header["host"], but it's not exposed in any of the Subject Areas or variables so there's no way to pull this onto an Analysis.

select	 "ASK_DEPLOYED_DOMAINS"."EXTERNAL_VIRTUAL_HOST" as "EXTERNAL_VIRTUAL_HOST",
	 "ASK_DEPLOYED_DOMAINS"."DEPLOYED_DOMAIN_NAME" as "DEPLOYED_DOMAIN_NAME",
	 "ASK_DEPLOYED_DOMAINS"."EM_HOME_URL" as "EM_HOME_URL" 
 from	"FUSION"."ASK_DEPLOYED_DOMAINS" "ASK_DEPLOYED_DOMAINS"
