Allow dropping _max time-series from Timer

[SHxKM]

Please describe the feature request.
Micrometer should allow its user to configure a Timer without the _max time-series. It is not always needed, unlike _count and _sum. For our company, this time-series is completely useless, and we're paying a heavy tax on it.

Rationale
We're admittedly scraping much data, but we saw that eliminating {timer}_max shrunk the /metrics endpoint response size by over 35% when Timers are the dominant metrics.

Additional context
We're using Micrometer with Prometheus and Spring. I can instead create two separate counters, one for duration and one for invocations, but the Micrometer docs clearly state you should never use a counter where you need a Timer.
