Change the logic of generating the D-Bus object identifier
Presently D-Bus object identifier is generated with the hash of
D-Bus properties, as a result of this if the value of D-Bus property
gets change the D-Bus object identifier will get change.
This commit fixes this problem by keeping the last identifier
value in the manager object so whenever user creates new snmp
manager object it is incremented by 1, hence the object path
becomes unique.
This commit also takes care of that if at any point of time
if snmp manager app restart it gets the same D-Bus identifier
as it was before the restart.
