moved python examples to jenkins wiki

Removed python examples from this java project.  The examples were using the
python 'gearman' library.  New examples using jeblair's 'gear' library have
been created on the jenkins gearman plugin wiki at
https://wiki.jenkins-ci.org/display/JENKINS/Gearman+Plugin

changed to python 'gear' because it's better than the gearman library.
