Command releasebot runs a Go release.

The release happens in two stages:

• the prepare stage checks preconditions, and if needed makes the release commit and mails it for review;
• the release stage runs after the release commit (if any) is merged, and it tags, builds and cleans up the release.

At the moment only minor and beta releases are supported.

The user running a release will need:

• A GitHub personal access token with the public_repo scope in ~/.github-issue-token, and an account with write access to golang/go
• gomote access and a token in your name
• gcloud application default credentials, and an account with GCS access to golang-org for bucket golang-release-staging
• release-manager group membership on Gerrit

NOTE: all but the Gerrit permission are ensured by the bot on startup.
