@philwebb this one is a bit interesting as to where the "home" for the auto-configuration should go for "DiskSpaceMetrics". It is in the Micrometer JVM package but feels a bit more like "System" metrics.

2 reasons I landed it in the JvmMetricsAutoConfiguration: - I rooted it to user.dir which is the current working directory the JVM was launched from - the metrics implementation uses methods on File that are from the viewpoint of the VM. For example, from File.getUsableSpace : > Returns the number of bytes available to this virtual machine on the partition named by this abstract pathname

Fixes gh-25996
