This commit adds some basic metrics and integration tests.
System wide metrics:
- units_by_type_total: target/device/automount etc.
- units_by_state_total: active/reloading/inactive etc.
Two per unit metrics which shows the current state of a unit:
- unit_active_state
- unit_load_state
A metric for service state:
- nrestarts
Here are some sample outputs:
