grizzly: Remove references to previous releases

[Tom Fifield]

When grizzly is ready to roll, go through the documentation to remove/update references from previous releases.

Suggested technique to begin finding areas that need update:
grep -Ri folsom *
grep -Ri essex *

    Remove Essex/Folsom cruft from Grizzly guides

    partially fixes bug 1087484

    With Grizzly a couple months away, the documentation team is working
    on its documentation as a priority. As part of the release of new
    documents, references to previous releases that are no longer useful
    or relevent should be removed.

    This change:
    * removes reference to pre-essex legacy options on keystone import
    * removes deleted simple scheduler from glossary
    * clarifies XenAPI pools for current status
    * removes note about Essex client mismatch in reset-stat
    * removes references to Essex and Diablo from dodai-deploy docs
    * removes an outdated (Essex) configuration file example
    * updates several links to point to Grizzly versions
    * removes outdated (Essex) ISO distribution information
    * removes outdated (Diablo, Essex) vnc proxy information
    * updates guide titles and versions where appropriate
    * removes old notes about config syntax
