Creation of the new DataCollector reporter

The DataCollector reporter is a new method for exporting data about your
Chef run. The details of this new feature can be found in
[RFC 077](https://github.com/chef/chef-rfc/blob/master/rfc077-mode-agnostic-data-collection.md).

Using the existing `EventDispatch` mechanics, the DataCollector reporter
collects data about a Chef run (when it starts, when it ends, what
resources were modified, etc.) and then POSTs them to a Data Collector
server URL that can be specified in your Chef configuration.

While similar functionality exists using the `ResourceReporter` and Chef
Reporting, a new implementation was done to decouple the reporting of this
data from requiring the use of a Chef Server (in the case of Chef Reporting),
opening the door to users being able to implement their own webhook-style
receiver to receive these messages and analyze them accordingly.
