climate is changing nova default filters if installed by devstack

[Guangya Liu (Jay Lau)]

After climate was installed by devstack, it was changing nova default scheduler filters

scheduler_available_filters = climatenova.scheduler.filters.climate_filter.ClimateFilter
scheduler_default_filters = ClimateFilter

But the default scheduler filters for nova is the following after installed by devstack without climate.
scheduler_available_filters = nova.scheduler.filters.all_filters
scheduler_default_filters = RetryFilter, AvailabilityZoneFilter, RamFilter, ComputeFilter, ComputeCapabilitiesFilter, ImagePropertiesFilter, ServerGroupAntiAffinityFilter, ServerGroupAffinityFilter

So after installed devstack with climate, nova scheduler filters should be as following:
scheduler_available_filters = climatenova.scheduler.filters.climate_filter.ClimateFilter
scheduler_available_filters = nova.scheduler.filters.all_filters
scheduler_default_filters = RetryFilter, AvailabilityZoneFilter, RamFilter, ComputeFilter, ComputeCapabilitiesFilter, ImagePropertiesFilter, ServerGroupAntiAffinityFilter, ServerGroupAffinityFilter, ClimateFilter

    Do not change nova scheduler filters after installed climate

    After climate was installed by devstack, it was changing nova default
    scheduler filters:
    scheduler_available_filters = climatenova.scheduler.filters.climate_filter.ClimateFilter
    scheduler_default_filters = ClimateFilter

    But the default scheduler filters for nova is the following after
    installed by devstack without climate.
    scheduler_available_filters = nova.scheduler.filters.all_filters
    scheduler_default_filters = RetryFilter, AvailabilityZoneFilter,
    RamFilter, ComputeFilter, ComputeCapabilitiesFilter, ImagePropertiesFilter,
    ServerGroupAntiAffinityFilter, ServerGroupAffinityFilter

    So after installed devstack with climate, nova scheduler filters should
    be as following:
    scheduler_available_filters = climatenova.scheduler.filters.climate_filter.ClimateFilter
    scheduler_available_filters = nova.scheduler.filters.all_filters
    scheduler_default_filters = RetryFilter, AvailabilityZoneFilter,
    RamFilter, ComputeFilter, ComputeCapabilitiesFilter, ImagePropertiesFilter,
    ServerGroupAntiAffinityFilter, ServerGroupAffinityFilter, ClimateFilter
