Inherit old jira cookbook from Opscode^WChef Software, Inc.

Chef Software, Inc. no longer uses JIRA, and the cookbook was so old
anyway (supporting EOL JIRA 3.3.x) that it was basically useless.
I've nuked-and-paved it with what I used to have here; this is the
initial commit of the nuke-and-pave. More improvements are to come.
