generic support for ondemand.d files

[johrstrom]

Right now this role writes out all the ondemand.d configurations into a single file ondemand.d/ondemand.yml in this task -

ood-ansible/tasks/configure.yml

Lines 32 to 36 in 3fddba1

	- name: Template ondemand.yml
	ansible.builtin.template:
	src: "ondemand.yml.j2"
	dest: "{{ ood_base_conf_dir }}/ondemand.d/ondemand.yml"
	mode: 'u=rw,g=r,o=r'

Instead what this should do is have the ability to write out multiple files each with it's own ownership flags. This would mimic the puppet behavior that's both easier to use and more flexible to deploy.
