*: only use docker when releasing, update to Go 1.8, remove aci scripts

This change modifies our release process to only require Docker
when building a release and updates our released binary to use Go
1.8. It also removes our .aci scripts, which we've not been
regularly building.

A nice consequence is that OSX users can now build a release image.

*: update go-oidc and use standard library's context package

examples/grpc-client: minor corrections in the dex client example.

storage/kubernetes: fix conflict error detection in TRP creation

PR #815 fixed the Kubernetes storage implementation by correctly
returning storage.ErrAlreadyExists on POST conflicts. This caused a
regression in TPR creation (#822) when some, but not all, of the
resources already existed. E.g. for users upgrading from old
versions of dex.

Fixes #822
