* CloudWatch: Datasource improvements * Add statistic as template variale * Add wildcard to list of values * Template variable intercept dimension key * Return row specific errors when transformation error occured * Add meta feedback * Make it possible to retrieve values without known metrics * Add curated dashboard for EC2 * Fix broken tests * Use correct dashboard name * Display alert in case multi template var is being used for some certain props in the cloudwatch query * Minor fixes after feedback * Update dashboard json * Update snapshot test * Make sure region default is intercepted in cloudwatch link * Update dashboards * Include ec2 dashboard in ds * Do not include ec2 dashboard in beta1 * Display actual region
