changed method for updating the cache to get, because ci didn't present
the html in a right way, and so the button was not functional
new URL to update: $JENKINS_URL/ccr-update/updateCache
removed the application select and the application variable
at building the job it is no longer possible to choose anything, all the
configuration for the parameter is done at configuring the job
added option to add a own parameter, the value for the parameter is
chosen by clicking through the hierarchy of the ccr
modified the way the cache manager downloads and creates the local cache
added the new variables to the value.jelly
