Update threshold to entity-manager

Save path&interface when creating thresholds,and then set DBUS value
corresponding to path&interface when setting thresholds;

I have a requirement to set the threshold to restart without losing.  In
addition, I can see that the threshold can be saved in the file in the
entity-manager, which can meet my requirements.

Data flow:
Old version: IPMI set threshold -> virtualsensors (DBUS) What
I want to achieve: IPMI set threshold -> virtualsensors (DBUS) ->
filesystem

I found that it can be implemented as follows: IPMI set
threshold -> virtual-sensors (DBUS) -> entitymanager -> filesystem

Because the threshold setting in dbus-sensors is: IPMI set threshold ->
dbus-sensors (DBUS) -> entitymanager -> filesystem

Tested:

The following print result shows this process:
IPMI set threshold -> virtual sensors (DBUS) -> entitymanager
