placement api root resource is only '/' not '' which can lead to unexpected 404s

[Chris Dent]

The placement api handler for root is defined as matching '/'. This works fine in those situations where the requested URL actually includes the '/' but in some situations it can be easy to not include it. If, for example, the API is mounted under a prefix like '/placement' (as in the default devstack setup) then it is possible to make a request to http://example.com/placement and get a 404 whereas http://example.com/placement/ will get the expected microversion information.

This ought to be easy to fix and was basically an oversight.

    [placement] Allow both /placement and /placement/ to work

    When mounted under a prefix (such as /placement) the service was
    only returning the home document at /placement/ not /placement. In
    the context of having a prefix, we'd generally like the latter to
    work and for '/' to work when there is no prefix. This allows both.

    Note that this doesn't make /placement/resource_providers/ work, and
    we don't want that.
