website: address spelling mistakes

The example error message being in here is important so people can search for that error message and find the answer easily. The default in my VirtualBox is V1, so many people will run into this.

This adds two config options that we need in order to successfully build
our Rackspace images.

First, a boolean `rackconnect_wait` option which waits for the
RackConnect metadata to appear.

Second, an `ssh_interface` option, for rackconnect users who have more
prohibitive firewalls on the 'public' interface and want to ensure all
traffic to the server goes over the 'private' one.

Finishes #952.

Clarify error message in case of an atlas client connection failure

When a packer json contains an atlas postprocessor, and `packer validate` runned locally
in case of the missing ATLAS_TOKEN env var, the following error message is displayed:

* Error initializing client: authentication failed

It wasn't clear which plugin produced this message, so the amazon-ebs builder was the suspect

Add Atlas post-processor documentation
