Add explicit module-info about micrometer

[bowbahdoe]

This isn't possible without a new major version. I don't foresee that happening anytime soon.

Ways 2 or 3 it is.

Isn't a prerequisite of adding an explicit module-info.java that all dependencies we declare have at least an automatic module name? In micrometer-core, I see our dependencies don't:

Okey dokie. Further into the mines I go.

I opened a PR on HDR histogram. Its last release was 4 years ago and they do have an automatic module name in their POM so maybe there just hasn't been a release since that.

After that, LatencyUtils (since it depends on HdrHistogram) https://github.com/LatencyUtils/LatencyUtils

A non-trivial part will be having those folks make maven central releases too.

We will have the same issue with some of the registry modules that have external dependencies.

One thing at a time I guess.

@bowbahdoe HdrHistogram 2.2.1 is now released to maven central with your PR integrated. I can also do the same to LatencyUtils if you open a PR there.

Bump the entire project to a higher Java version.
