GCP support now in gcp.upspin.io

[Andrew Gerrand]

Hi Upspinners,

We just completed some work to move the Google Cloud Platform-related code from the core upspin.io repository into a new repository at gcp.upspin.io.

You may be affected if:

- you are running upspinserver with a Google Cloud Storage backend (configured with "upspin setupstorage"), or

- you are running an Upspin service on a GKE cluster (deployed with "upspin-deploy").

If you are running upspinserver with Google Cloud Storage, you must now use upspinserver-gcp when updating. To download it and its dependencies, run:

  $ go get -d -u gcp.upspin.io/cmd/upspinserver-gcp

And to build it, run:

  $ GOOS=linux GOARCH=amd64 go build gcp.upspin.io/cmd/upspinserver-gcp

When updating the upspinserver on your server, you should copy the upspinserver-gcp binary in its place. 

If you are running an Upspin GKE cluster, you must now use upspin-deploy-gcp to update your cluster. To download and install it, run:

  $ go get -u gcp.upspin.io/cmd/upspin-deploy-gcp

You can safely delete the old upspin-deploy binary. It won't work correctly anymore.
