Donal McBreen 9089c41f30 Add secrets-common for shared secrets
Add a shared secrets file used across all destinations. Useful for
things Github tokens or registry passwords.

The secrets are added to a new file called `secrets-common` to highlight
they are shared, and to avoid acciedentally inheriting a secret from the
`secrets` file to `secrets.destination`.
