Job configurations file should be in git repo not in each project but
as we maintain our ansible repo which is common for our complete Infra
same way we have to create a JJB repo which will be common across all
project which suppose to be on Jenkins.

If you want to ignore some project then don't include it in project
section[0] and JJB will ignore it then you still have choice to use
manual configuration using jenkins-web. Like Ansible make sure our
infra servers should be in desired state (if not we run playbook
again) same way JJB make sure our Jenkins jobs are in desired state
and we don't have to write template of a particular project which we
want to maintain manually (like we don't have to write playbook if we
want to manage a server manually).
