HostManager doesn't have get_host_list() method

[Kiyohiro Adachi]

cinder.scheduler.host_manager.HostManager doesn't have get_host_list()
and get_service_capabilities() method.

But I look like which cinder.scheduler.driver.Scheduler is trying to call them.
Are they not being used? I think they can be deleted.

    remove unused methods in driver.Scheduler

    cinder.scheduler.host_manager.HostManager doesn't have get_host_list()
    and get_service_capabilities(). But we don't catch the AttributeError
    by them. Therefore, get_host_list() and get_service_capabilities() in
    cinder.scheduler.driver.Scheduler have not been used.

    Also, get_host_list() and get_service_capabilities() in
    cinder.scheduler.manager.SchedulerManager have not been used.
