devstack should disable resize tests in tempest if using cells

[Matt Riedemann]

Resize tests in tempest fail when using devstack because by default devstack/lib/tempest creates it's own flavors for testing which are not in the cells database.

This can be seen here:

The gate-tempest-dsvm-cells job (using nova-network) gets around this by skipping all of the resize related tests:

https://github.com/openstack/nova/blob/master/devstack/tempest-dsvm-cells-rc

We need to remove those and handle the config in devstack.

    Disable resize tests in Tempest if using cells with custom flavors

    By default, devstack creates it's own test flavors for Tempest runs.

    These are not in the cells API database since they are non-default
    for nova so any resize tests in Tempest with cells and these custom
    flavors fail.

    Configure Tempest to not run resize tests if using cells and custom
    flavors.

    This allows us to also clean up a bunch of the resize skips found
    in nova/devstack/tempest-dsvm-cells-rc.
