Capture Region of Executing Process as part of analytics data
In the analytics schema, we have fields cloud_RoleName and cloud_RoleInstance. When an application is deployed to multiple regions and each deployment is using a single instrumentation key, it would be useful to split data by the cloud geographic region that processed the telemetry,
e.g. cloud_GeoRegion, to contain data such as 'West Europe', 'West US', 'UK West' etc.
This would apply to any of the schemas, where cloud_RoleName and cloud_RoleInstance are recorded.
