Based on Molecule testing fix following issues on
nfs role.

 - enable nfs services (previously only started)
 - create handler for exportfs to deal idempotency
 - add all kubernetes nodes to exports as it was dependent on ansible inventory order wheather correct hosts was on the list
 - add inventory_hostname as default host incase ansible_host variable not defined.
