placement allocations handler module does not use util.extract_json

[Chris Dent]

nova.api.openstack.placement.handlers.allocation uses and _extract_allocations method which could be remove in favor of nova.api.openstack.placement.util:extract_json

A nice tidy up, leaving as a bug as a reminder to cdent or a low hanging fruit for someone else to pick up.

    [placement] Use util.extract_json in allocations handler

    The handler had its own version of the exact same code, so may as
    well use the utility method.

    Nothing changes at the API level with this change. Error messages
    and response codes remain the same.
