Assess desired inter-project dependency behavior, deficiencies
### Discussion Topic
"Why isn't it easy to just move this or that XML/primitive/worker/assembly from one project to another?"
Create list of all specific problems which prevent this.
* component specs are not exportable across projects
* containers are not exportable across projects (opencpi#823)
* workers instanced within an assembly cannot be package ID-qualified (opencpi#459)
* primitive export/import problem proja/hdl/primitives -> projb/hdl/platforms/foo/ (opencpi#1102)
* device workers can not exist in multiple projects with the same name
- examples: `ocpi.assets.devices.ad9361_config`, `ocpi.platform.devices.platform_ad9361_config` - the `platform_` should not be necessary
