split go-uaa

[joefitzgerald]

Per the instructions in #801 (comment), this splits go-uaa from the rest of the UAA repos so that I can continue to merge PRs as the original author and maintainer of the library.

@Tallicia someone from your company should check because you use it more than we

@strehle please review the context from #801 (comment). In summary:

• I created the go-uaa library
• I maintained it, and worked with the UAA team to integrate it into the UAA CLI while I was at Pivotal
• The UAA team has turned over a few times since then, but I have remained a maintainer of the library; I still aspire to have the UAA / identity team maintain the library but I remain a backstop for merging of PRs that are left open for too long
• The repo was moved without consultation from the cloudfoundry-community org (where I was an org owner) to the cloudfoundry org (where I did not have any commit rights), resulting in me losing the ability to maintain the library
• This PR restores my ability to maintain the library
