Summary
We have not used full screenshot image data since early alpha versions of Synthetics (pre 7.14.0), and there is no reason to not use screenshot blocks instead as they make far more efficient storage performance.
Release note
Removes support for Heartbeat browser monitor screenshots for lower versions of Heartbeat. Please upgrade to Heartbeat 7.17.24 to continue using Heartbeat browser monitor screenshots.
Testing
Screenshots are just for browser monitors, and browser monitors are in Beta in 7.17.x and will never be moved to GA. I don't believe this ticket needs additional testing beyond passing integration tests.
