Resolves issue #291

This reduces the system metric collection time by using a wait group
and go routines to allow the systemd metric calls happen concurrently.
Also, makes the start time, restarts, tasks_max, and tasks_current metrics disabled by default
because these can be time consuming to gather.

Adds a new label called "type" systemd_unit_state which contains the
Type field from the unit file. This applies only to the .service and
.mount unit types. The other unit types do not include the optional
type field.
