v0.6.0

What's Changed

• Added a RunBackgroundCleanup method to the Prometheus sink that periodically clears expired metrics if they are not collected. This is available only with the hashicorpmetrics build tag.
• DataDog metrics will now include a trailing newline, allowing dogstatsd agent operators to enable truncation detection via dogstatsd_eol_required.
• Dependency and toolchain updates to bring dependencies current on upstream security updates.
