Move to new association interface

A new association interface is defined in phosphor-dbus-interfaces
It would be nice to move the local version of the interface
to the new one.

The behavior of how association work is described here:
https://github.com/openbmc/docs/blob/master/object-mapper.md#associations

Partially resolves openbmc/openbmc#3584

Tested: See the org.openbmc.Associations interface has been replaced by the xyz
one in /xyz/openbmc_project/software/version_id object
