merge host metric tests into single infra test

[movence]

Description of changes

Refactor test/metric_value_benchmark/ to consolidate the 9 individual infra metric plugin configs (cpu, mem, disk, diskio, net, netstat, swap, processes, procstat) into one unified agent config and one runner that validates all infra metrics in a single agent start/stop cycle. Then run this same metric_value_benchmark test from the localtest Docker container.
