Fix PSU threshold mismatch issue

When trying to change thresholds on PSU sensors, PSU service will crash.
Some PSU in entity-manager will have threshold0 to threshodl5 which
contains all labels in one D-Bus path. But in current dbus sensors,
the presist threshold function do not support labels, it only check
severity. So when change a threshold in PSU sensor, it will change some
incorrect threshold in entity-manger. This patch adds label support to
presist threshold function, so that correct theshold in entity-manager
can be changed.

Tested:
After changed PSU1 Temp1 threshold by ipmitool, check the threshold again,
the value should be changed to the value we set. Check entity-manager,
the threshold in entity-manager should also change to the value we set.
