New Form Styling for AWS data sources

AWS data sources have migrated to new form styling in Configuration and Query editors in order to comply with the Grafana design system guidelines (found here) . This feature enables Public Preview of the migrated forms for AWS data sources:

Cloudwatch
X-Ray
Athena
Redshift
Sitewise
Twinmaker

It includes the following changes:

revamped data source configuration forms, including block input fields, descriptions and separated sections
a new look and feel for data source query editors

The data sources must be updated to their latest versions in order to make use of the feature.
