Radosław Piliszek 266fd61ad7 Use "name:" instead of "role:" for *_role modules
Both include_role and import_role expect role's name to be given
via "name" param instead of "role".
This worked but caused errors with ansible-lint.

# This playbook is for nova services. Due to support for deployment of cells,
# nova is separated into two roles - nova and nova-cell. This makes it more
# complicated than other services, as we may execute each role several times
# for a given operation.
#
# The nova role now deploys the global services:
#
# * nova-api
# * nova-scheduler
# * nova-super-conductor (if enable_cells is true)
#
# The nova-cell role handles services specific to a cell:
#
# * nova-compute
# * nova-compute-ironic
# * nova-conductor
# * nova-libvirt
# * nova-novncproxy
# * nova-serialproxy
# * nova-spicehtml5proxy
# * nova-ssh
# We need to perform database bootstrapping before deploying or upgrading any
# containers, to ensure all database schema migrations have been performed,
# both in the API and cell databases. Note that this should not be disruptive
# to the Nova services, which will continue to run against the new schema.
