Fix Alpine Linux disk usage metrics

Added

• When the AppSignal log level is set to "trace". Additional information from the OpenTelemetry instrumentations is now logged.

Changed

• Fix disk usage returning a Vec with no entries on Alpine Linux when the df --local command fails.

Removed

• Remove the appsignal_set_host_gauge and appsignal_set_process_gauge extension functions. These functions were already deprecated and did not report any metrics.

Fixed

• Fix the demo sample recognition. Demo samples didn't show the helpful explanation box in the UI, because the demo_sample tag was set incorrectly as an attribute.

See the Node.js 3.0.30 package changelog for more information.
