Handle recursive resources within a device profile (command chaining)

[iain-anderson]

Instead of containing a reference to a device resource (the device resource's name is in the "object" field), a resourceoperation may refer to other (profile) resources. In this case the "resource" field will be set to the name of the profile resource.

See the sample profile DENT.Mod.PS6037.profile.yaml in device-modbus for an example.

This would be a good time to enhance the device profile reading code so that it resolves resource/deviceresource names when profiles are loaded.
IE, edgex_resourceoperation.object becomes an edgex_deviceresource*
and edgex_resourceoperation.resource becomes an edgex_profileresource*

Not happening for Geneva (was not committed in scope)

Agreed in Levski planning meeting that this would not be implemented. Note that the fields specifying nested device commands were removed in the profile rework for EdgeX 2.0
