* make update-workspace
Fix unexpected error when creating a new cloudwatch datasource.
Involves a fair amount of refactoring, so if this causes unexpected issues related to region fetching we can turn this off with the cloudwatchNewRegionsHandler feature toggle, although we do not predict it will so we are enabling it to default to true and hope to remove it shortly.
* Create minimal EC2 interface
* convert regions variable to a function returning a copy
* Add test for multiple calls to regions to check regionsCache
* Add returns to handler after error
* Refactor handleGetRegions
* cleanup cloudwatch.go
* streamline interface naming
* use utility func
* rename test utils file
* move util function to where they are used
* move dtos to models
* split integration tests from the rest
* Update pkg/tsdb/cloudwatch/cloudwatch.go
