JSON output for SimpleTimer is always in seconds; it should be expressed in whatever units are set in the metadata

Problem Description

JSON format output should express data values in the units defined in the metadata for the metric. For SimpleTimers the JSON-formatted elapsedTime is always expressed in seconds, regardless of the units specified in the SimpleTimer's metadata.

Steps to reproduce

Create a HelidonSimpleTimer (our implementation of SimpleTimer) specifying something other than seconds as the units in the metadata. Update the simple timer with some value. Invoke the HelidonSimpleTimer#jsonData method. The elapsedTime key in the resulting JsonObject will be incorrectly expressed in seconds.
