Add Go lib support (for Buildpacks)

[dfreilich]

The Cloud Native Buildpacks project is considering adding support for notary v2, potentially in https://github.com/buildpacks/lifecycle when constructing images (either as part of our current phases, or as a new phase, depending on project decisions). As such, we will need Go lib support, in order to utilize it as part of the lifecycle.

Thanks @dfreilich,
This is a great issue to track. You'll start seeing PRs to https://github.com/notaryproject/notary/ which is designated as the repo for libraries. See: notaryproject/notary#2 for an example.
The /notaryproject/nv2 repo will be for notary v2 binaries, that implement the libraries.

I'm going to transfer this issue from notaryproject/nv2 to notaryproject/notary

@dfreilich This issue has been open for a long time. There are two repos of go libraries for notary v2 now. Could you check whether it meets your requirement?

• https://github.com/notaryproject/notation-go/
• https://github.com/notaryproject/notation-core-go/

@dfreilich is this issue still valid? We now have stable versions of Go libraries.
