Sync product group_vars from repo to /etc

[LukeRepko]

Is your feature request related to a problem? Please describe.
When updating group_vars for a given product, e.g. ansible/inventory/openstack-flex/group_vars/k8s_cluster/k8s-cluster.yml they will not take effect in subsequent kubespray operations unless the bootstrap script is run or those group_vars are manually updated.

Describe the solution you'd like

Describe alternatives you've considered
