Alexander Reelsen 04a8fb3202 Watcher: Add chained input
```
Chained input for now works like this
{
"chain" : [
  { "first" : { "simple" : { "foo" : "bar" } } },
  { "second" : { "simple" : { "spam" : "eggs" } } }
]
```

This allows to access the payload via ctx.payload.first.foo for example

The array notation is needed to guarantee order, as JSON itself does not guarantee
order of objects.

Closes elastic/elasticsearch#353
