Add Go lib support (for Buildpacks)

[SteveLasker]

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?
