Move check-jinja2 jenkins job to pharos project

Move check-jinja2 jenkins job to pharos project

Securedlab will be going away now that we can encrypt strings
(eyaml)

we need to check jinja2 PDF templates that will be moving into pharos
This adds a jenkins job to check those templates

After This change and https://gerrit.opnfv.org/gerrit/#/c/47735/ are merged
I can start moving pdf files into the pharos repo

Once this is complete I can remove check-jinja2 job from securedlab.
Eventually decommissioning the securedlab repo
