Re-usable CLI flags for cargo plugins

// ...
#[derive(Debug, clap::Parser)]
struct Cli {
    #[command(flatten)]
    manifest: clap_cargo::Manifest,
    #[command(flatten)]
    workspace: clap_cargo::Workspace,
    #[command(flatten)]
    features: clap_cargo::Features,
}

Other crates that might be useful for cargo plugins:

• escargot for wrapping cargo-build, carg-run, cargo-test, etc.
• cargo_metadata for getting crate information.
• clap-verbosity for adding logging to your CLI.
