 * @deprecated Will be removed in v8. To create a connectable observable, use {@link connectable}.
 * `source.pipe(publish())` is equivalent to
 * `connectable(source, { connector: () => new Subject(), resetOnDisconnect: false })`.
 * If you're using {@link refCount} after `publish`, use {@link share} operator instead.
 * `source.pipe(publish(), refCount())` is equivalent to
 * `source.pipe(share({ resetOnError: false, resetOnComplete: false, resetOnRefCountZero: false }))`.
