Azure: get instance id from dmi instead of SharedConfig

Replace the use of SharedConfig.xml in both the walinuxagent case,
and the case where we communicate with the Azure fabric ourselves.

The instance id present in the dmi data is unfortunately different
that that in the SharedConfig.  This means that something needs
to handle migration so that a reboot after newer version is installed
will not re-run first instance things.

In Ubuntu this is being handled in packaging.
