Fixed typo in example documentation

Remove code underlying when_* and only_if, which are deprecated features slated for removal in the 1.5 release.

Resolves issues with newer versions of pip not having a --use-mirrors paramater for the install command

We have had only_if, when_foo, etc, deprecated for a while and said they would be removed in 1.5.  Now they are, with friendly error messages still.

Users of these features should use "when:" as documented at docs.ansible.com.

Similarly, include + with_items has been removed.  The solution is to loop
inside the task files, see with_nested / with_together, etc.

Fix documentation example for the fail module

The example for the fail module doesn't work:
  http://www.ansibleworks.com/docs/modules.html#fail

The current text shows:
    - fail: msg="The system may not be provisioned according to the CMDB status."
      when: "{{ cmdb_status }} != 'to-be-staged'"

The "when" documentation indicates that the argument is already a Jinja2
expression:
  http://www.ansibleworks.com/docs/playbooks_conditionals.html#the-when-statement

Thus, the following is
      when: cmdb_status != "to-be-staged"

is preferred even though the following could work but generates a
deprecation warning:
      when: {{cmdb_status != "to-be-staged"}}
