RFE: Add a push() method about replicache

[mashpie]

I am tracking online and visibility state to replicache.pull() as soon UI is online or gets focus (ie. changed tap from background to foreground).

  /**
   * tracks changes on visibilitychange
   */
  document.addEventListener('visibilitychange', () => {
    if (document.visibilityState === 'visible') replicache.pull()
  })

  /**
   * tracks changes on network events
   */
  const online = useOnline()
  watch(online, (isOnline) => {
    if (isOnline) replicache.pull()
  })

so for a user all remote changes get pulled instantly. Same would apply for replicache.push() to propagate local changes. Waiting a couple of seconds is often confusing users.

What would the optional argument do?

I think at the time I was thinking it would be "right now" vs "soon". But I guess that's not needed since by default we push soon.
