In order to improve the getting started experience, we'd like to add sample data to Kibana to power APM + Infra + Logs so users can get hands on with them. Edit: leave infra/logs/uptime for a follow on effort.

#17807 originally added sample data into Kibana, so could help as a reference for implementation.

Logs UI already supports the sample data index (kibana_sample_data_logs) by default, so populating that index should just work.

Infra UI also includes the logging sample index by default but not one for metrics.

APM UI does not include a sample data index by default. #39741 could fit in nicely to enable that. edit: use an index name that matches the exist pattern

See #40704 (comment) for more implementation details
