The grafana plugin SDK bundles build metadata into the binaries it compiles; this metadata includes the repository URI for the plugin being built, as retrieved by running `git remote get-url origin`. If credentials are included in the repository URI (for instance, to allow for fetching of private dependencies), the final binary will contain the full URI, including said credentials.
