Scheduler requests unlimited results from placement

Bug Description

The scheduler will request an infinitely-large host set from placement during scheduling operations. This may be very large on big clouds and makes for a huge JSON response from placement to scheduler each time a single host needs to be selected.

    Pass limit to /allocation_requests

    This makes us pass an upper limit to placement when doing scheduling
    activities. Without this, we'll always receive every host in the
    deployment (that has space for the request), which may be very large.
