    Add nova-manage cell_v2 create_cell command

    Currently, all of the commands that create a new cell require the
    presence of compute hosts, else they won't create a cell mapping.
    In the use case of a fresh install, it's reasonable that compute
    host records may not yet exist at the time of cells v2 setup.

    This provides a way for operators to create a new empty cell at
    setup time and defer adding hosts to the cell until they have
    started their compute hosts later (via the 'discover_hosts'
    command).

    The command optionally accepts a database connection url and
    message queue transport url, else it will take the values from
    the nova.conf. It returns the uuid of the newly created cell.
