Consider changing telemetry format

[tristanls]

Instead of emitting individual events like:

stats.timers.find.ms
stats.timers.find.round.ms

perhaps instead emit a single telemetry event with content being self-describing:

module=discover.target_type=timer.operation=find.unit=ms 10
module=discover.target_type=timer.operation=find_round.unit=ms 2

alternatively:

module=discover target_type=timer operation=find unit=ms 10
module=discover target_type=timer operation=find_round unit=ms 2

alternatively:

module=discover&target_type=timer&operation=find&unit=ms&10
module=discover&target_type=timer&operation=find_round&unit=ms&2
