Support tuned in compute-init (#570)

* document which roles require an image build for compute_init

* fix compute-init docs for node-exporter

* reorder compute-init docs notes

* add tuned into stackhpc image

* match /mnt/cluster permissions before and after mount, so ansible-init reruns don't fail

* support tuned in ansible-init

* enable tuned for stackhpc rebuilds

* allow injecting ark creds even during site.yml, for development use

* bump CI image
