Discovery method that takes a list of hosts to connect to and to
reconnect to if a connect is lost. Reconnection can be disabled by
including the option `refresh_interval_ms => infinity` when starting
`gen_cluster`.

This is a built-in discover implementation so has a short name,
`static`, as well.
