internal/secret: add secret management package
This change adds a package which can be used to retrieve secrets from
GCP Secret Management Service. The goal of this package is to ensure
that there is a simple and known way to retrieve secrets for any
service housed in the build repository. This package should enable the
storage of the project secrets in a single, secure location.
A simple use of the package is introduced to the scaleway application.
Updates golang/go#37171
