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"}}

added more usefull example for jinja2 overrides 

Missing "is" in file module description

Updated main description to state that the yum module will handle package groups.  Added descriptions for each example, as it is unclear to (some) users that @Name implies a group install.
