Create Interface returns the D-Bus object path

In current code when the client creates the SNNP manager D-Bus object,
snmp-conf-manager(D-Bus service) implementing the create interface
was not returning the newly created D-Bus object path, hence
client needs to make the enumerate call on the
network namespace to find the newly create D-Bus object path.

This commit fixes this problem where Create interface starts
returning the newly created D-Bus object path.

Resolves openbmc/phosphor-snmp#1
