The ``scheduler_available_filters`` option is being deprecated in favor of
``scheduler_enabled_filters``. The new name is more indicative of what the
option means. ``scheduler_enabled_filters``'s default value is set to the
default value of Nova's ``enabled_filters``.
``scheduler_available_filters``'s default was `all`. There was confusion
around this value. Sometimes it was understood to mean the default Nova
filters are enabled, other times it was understood to mean all filters are
enabled. While `all` is still allowed for ``scheduler_enabled_filters`` for
backwards compatibility, it is strongly recommended to provide an explicit
list of filters that matches what's configured in nova.conf.
