Migrate JFR parameter recording-template to jfr-recording-template

[debanjanc01]

Currently the recording-template for the jfr telemetry device does not have the jfr prefix to it. This namespace should be added to keep it in line with parameter definitions for other telemetry params.

This is raised in reference to https://github.com/elastic/rally/pull/1630#discussion_r1028045952
