Resolve "Cloning the submodule triggers errors from github"

Closes #13

See merge request jpr/ohpc_vagrant!31

The default was to use ssh urls for github which require an account
on github. Switch to the https url for the submodule to simplify
project clones for users without github accounts.

Resolve "post ansible staging of slurm.conf"

Closes #6

See merge request jpr/ohpc_vagrant!8

This configures the ood node to be a part of the slurm cluster.
It enables job execution, control and shell access to the headnode.

It turned out to be easy enough to add warewulf synchronization to
the ood node in cluster rather than use Vagrant to move files. This
also ensure future slurm.conf and other registered file changes are
maintained across cluster nodes after changes.

Note: `vagrant ssh ood "mount -a"` must be manually run after provision
to sync /home across cluster.

Fixes #6

Update submodule for upstream post merge commit.

Resolve "feature: add support for ood"

Closes #3

See merge request jpr/ohpc_vagrant!6

This introduces permissive selinux policy state and
avoids a reboot.

We need to be able to test both http and https configurations
since https with be the default for ood (http is only for dev).
Also remove the unused host rename config.

This is needed so that the ansible playbook is correctly
selected based on hostname.
