* Fixes#1938
Fixed usage of Telemetry API, use hints to get valueMetadata, use valueMetadata to get formatter
* dont circumvent chooseTelemetryKeyToDisplay, which was causing a regression when imagery is added to fp
* fix broken tests
* pass valueMetaData to limitEvaluator.evaluate, rename #chooseTelemetryKeyToDisplay to getValueMetadata, to reflect what is returned.
update tests
* change getValueMetadata to chooseValueMetadataToDisplay
