Takes a template file and feeds it values

Values come from a pod config file.
This is just an example, only ipmi_ips are templated at this time.

eg: address: {{ config['global_details']['ipmi_ips'][0] }}

test like this:

./utils/generate_config.py -y labs/intel/pod5/pod.yaml -j
installers/joid/labconfig.jinja2

releng should have a new job, validate-templates
that looks for
pattern: 'utils/generate_config.yml'
pattern: '**/*.jinja2'

and tests that templating does not error.
