New HTTP Client Processor Field for Ignoring Timeout Error

[gramian]

Dear All,
I would like to propose a new configuration field for the http client processor, which allows to ignore exceeded timeouts. This boolean field could, for example, be named ignore_timeout and be by default false. This field may or may not regard retries, however, after the first or last time-out respectively, no connection error is fired, but instead an empty object {} is passed down-stream.

- http:
    url: "http://10.0.0.0"
    verb: "GET"
    ignore_timeout: true

This is useful for requests that are expected to time-out. For example if a request triggers a long running action (think hours) with variable runtime, of which its state can be checked through other means.
