Bug Description

instance_get_all() joins a bunch of stuff by default that makes scheduling much slower than it needs to be. The scheduler doesn't use most of the information.

Improve filter_scheduler performance

    Add 'columns_to_join' keyword arg to instance_get_all() and have the
    scheduler host_manager only join 'instance_type'. It doesn't use
    anything else.
