Returns a specification to start this module under a supervisor.

See Supervisor.

Starts a :one_for_one supervisor with one child per configured transport.

The child spec that use Snodo.Server defines starts this supervisor. It takes :transports and :supervisor_name (passed here as :name) along with runtime overrides.

Options:

• :runtime - the Snodo.Server.Runtime given to every transport. Required.
• :transports - the transport children. Defaults to []. Each entry is a module, started as {module, runtime: runtime}; a {module, opts} tuple, started with :runtime added to opts unless already present; or a child spec map, used as given.
• :name - a name to register the supervisor under.
