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.

Having tagged plays allows us to easily run a subset of the plays for a
command, and perform targeted operations with less risk of unintended
consequences.
The tags are typically named after the playbook, although some of the
overcloud playbooks have been tagged without an overcloud- prefix.
Previously shared kolla-ansible's kolla_config_path, now uses
kolla_build_config_path.
Also adds a variable, config_path, which sets a base path for
configuration on the remote hosts.
In environments without Swift we are currently unable to store hardware
introspection data. The inspection_store container runs an nginx server
that supports a restricted Swift-like HTTP API using WebDAV that supports
upload and retrieval of introspection data.
