feat(snap): Remove device-virtual

[MonicaisHer]

This PR removes device-virtual for the following reasons:

• This app is for development/demonstration purposes only and not needed in production. It shouldn’t be shipped by default. It will become a standalone snap.
• The hardcoded versioning of the source inside the snap makes it hard to keep the edgex-go source compatible with device-virtual source. Upstream takes care of go vendor versioning but not snapcraft parts.
• The build and hooks logic adds avoidable complexity to the core snap. Removing device-virtual reduces edgex snap size from 293M to 283M.

Thanks. Looks good.

Tested together with edgexfoundry/device-virtual-go#287 and it works as expected.
