CBQE-0: add config LINUX_JOB_TEMPLATE.xml

this config for http://qa.hq.northscale.net/view/All/job/LINUX_JOB_TEMPLATE

http://qa.hq.northscale.net/view/All/job/LINUX_JOB_TEMPLATE/config.xml

it could be useful:
a) to track changes that have been made after
b) use python-jenkins to create new jobs based on template, like:

j = jenkins.Jenkins('http://your_url_here', 'username', 'password')
j.create_job('empty', CONFIG_XML)
