    Fix 500 if you pass invalid sort_key and sort_dir

    Host and failover segments list apis return 500 InternalServerError if
    you pass invalid sort_key or sort_dir.

    Caught exception.InvalidSortKey at controller level and also allowed
    multiple sort_keys and sort_dirs to pass.

    NOTE:
    Allowed to pass multiple sort keys to list apis.
    Also moved the processing of request parameters from masakari/ha/api.py
    to respective failover segments and hosts controllers as request parameters
    should be handled in controller itself.
