🚩 add the ability to store and watch synced data

[jpwilliams]

A really interesting little idea.

This adds the ability to use a new remit.watch command. It functions similarly to a listener, but is intended for a block of JSON synced between multiple processes.

// create the watcher
const watcher = remit
  .watch('my.synced.data')
  .handler(({ data }) => {
    console.log('got new data:', data)
  })

watcher.start()

// access the current data set
console.log('current data is:', watcher.state)

Multiple processes accessing the same my.synced.data there will all receive the same JSON block. To change it, any of the processes can send an emission to my.synced.data and all of the watchers will receive the update.

Testing it out in a tiny little environment with servers spinning up and down. It's a super-interesting little idea, though not sure how viable/useful it is in the real world.

This ran in to some fundamental problems and won't be possible until a few RabbitMQ versions in to the future.
