provide one command to extract parameters necessary to deploy DCN

[John Fulton]

A process is documented [1] to extract configuration from the control plane overcloud into multiple files to be used as input to subsequent DCN overcloud deployments. This LP bug tracks having tripleo-client provide a command to perform the extraction so that the user doesn't have to follow as many steps (though both processes should be supported).

Benefits of providing one command to do this include avoiding bugs like RHBZ 1762360 and simplifying operator experience.

Implementation of this change could be a variation of https://review.opendev.org/#/c/672070

If we use an include list I started one here that works for nova instances (but not storage like cinder)

    Add openstack overcloud export

    Add a new command to export the data from a control plane stack for
    multi-stack. The created export file can be used as input into a compute
    stack for the multi-stack feature.

    Also refactors the overcloud cell export command to use the same common
    code.
