This patch adds initial support for deploying multiple Nova cells. Splitting a nova-cell role out from the Nova role allows a more granular approach to deploying and configuring Nova services. A new enable_cells flag has been added that enables the support of multiple cells via the introduction of a super conductor in addition to cell-specific conductors. When this flag is not set (the default), nova is configured in the same manner as before - with a single conductor. 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 This patch does not support using a single cell controller for managing more than one cell. Support for sharing a cell controller will be added in a future patch. This patch should be backwards compatible and is tested by existing CI jobs. A new CI job has been added that tests a multi-cell environment. ceph-mon has been removed from the play hosts list as it is not necessary - delegate_to does not require the host to be in the play. Documentation will be added in a separate patch.
