History
Mark Goddard 4038c8226b Change reserved keyword 'action' to 'kayobe_action' 
For several roles (cadvisor, inspection-store, docker-registry, etc.),
we use an 'action' variable, in a similar manner to kolla-ansible,
to determine the current action being performed (deploy,
reconfigure, upgrade). It is likely this information will be
useful for custom playbooks, so we should expose it. The 'action'
keyword is reserved, and its use triggers a warning, so we change its
name to kayobe_action before advertising it to users.
