    API extension to list supported scheduler hints
    
    The Nova API for instance creation supports a scheduler_hints mechanism
    whereby the user can pass additional placement related information
    into the Nova scheduler.
    
    The implementation of scheduler_hints lies (mostly) in the various
    scheduler filters, and the set of hints which are supported on any system
    therefore depends on the filters that have been configured (this could
    include non-standard filters). It is not currently possible for a user
    of the system to determine which hints are available. Hints that are not
    supported will be silently ignored by the scheduler
    
    This API extension makes the list of supported hints available to users
    by querying each of the configured scheduler filters

    WIP - Some unit tests still needed but posted to see if there are any
    comments on the overall approach
