Make Timer and LongTaskTimer output similar in LoggingMeterRegistry

In case of the LoggingMeterRegistry, the output of a LongTaskTimer
looks like this:
"my.ltt{} active=30 duration=30m"
while the output of a Timer is something like this:
"my.timer{} delta_count=30 throughput=0.5/s mean=1s max=1s"

We can add the missing fields to the LongTaskTimer output:
"my.ltt{} active=30 duration=30m throughput=0.5/s mean=1m max=1m"
