Console log measurement name with conversion fun name

[03juan]

Hi there.

I noticed a discrepancy in the console logger:

The event logs the measurement name when there is no function

Metric measurement: :response_time (summary)

but only the inspected function name otherwise

Metric measurement: &Telemetry.Metrics.ConsoleReporterTest.metadata_measurement/2 (sum)

This fix proposes to always print the measurement name and include the function inspection as necessary.

---

This is especially problematic with the multiple recommended ecto repo summaries in the documentation:

# Database Time Metrics
summary("my_app.repo.query.total_time", unit: {:native, :millisecond}),
summary("my_app.repo.query.decode_time", unit: {:native, :millisecond}),
summary("my_app.repo.query.query_time", unit: {:native, :millisecond}),
summary("my_app.repo.query.idle_time", unit: {:native, :millisecond}),
summary("my_app.repo.query.queue_time", unit: {:native, :millisecond}),

Where all the events are logged as:

Metric measurement: #Function<... in Telemetry.Metrics.maybe_convert_measurement/2> (summary)
With value: ... millisecond
Tag values: %{}

Metric measurement: #Function<... in Telemetry.Metrics.maybe_convert_measurement/2> (summary)
With value: ... millisecond
Tag values: %{}

... etc. x3 more

Thanks for the consideration
